Information perseveration in recognition memory: Examining the scope of sequential dependencies.

Models of recognition memory often assume that decisions are made independently from each other. Yet there is growing evidence that consecutive recognition responses show sequential dependencies, whereby making one response increases the probability of repeating that response from one trial to the next trial. Across six experiments, we replicated this response-related carryover effect using word and nonword stimuli and further demonstrated that the content of the previous trial-both perceptual and conceptual-can also bias the response to the current test probe, with both perceptual (orthographic) and conceptual (semantic) similarity boosting the probability of consecutive "old" responses.

Note-taking for the win: Doodling does not reduce boredom or mind-wandering, nor enhance attention or retention of lecture material.

Doodling and fidgeting-traditionally viewed in educational contexts as markers of inattention and poor classroom behaviour-have more recently been considered as possible routes to improve performance by reducing boredom and its negative impact on memory. However, there is a surprising lack of well-controlled studies examining this possibility, despite the widespread adoption of fidget toys and doodling exercises within classroom settings. Here we report two experiments (total  = 222) that assess the impact of doodling on boredom, attention, mind-wandering, and subsequent recall of auditory information.

Subjective Impact of Age-Related Hearing Loss Is Worse for Those Who Routinely Experience Boredom and Failures of Attention.

Objectives: Despite extensive evidence supporting the benefits of hearing treatments for individuals affected by hearing loss, many leave their hearing issues unaddressed. This underscores the need to better understand the individual factors influencing decision-making regarding hearing loss treatments. One consideration regarding the low uptake of treatment is the finding that the subjective impact of hearing loss is greater for some individuals than for others, yielding a significant discrepancy between subjective measures of hearing loss (e.

Motor-response execution versus inhibition alters social-emotional evaluations of specific individuals.

Social-emotional evaluations of unfamiliar people are negatively impacted by ignoring or withholding motor-responses from images that depict them; an effect attributed to the propensity of inhibition to affectively devalue associated stimuli. Prior findings suggest that the social-emotional consequences of inhibition may operate on category-level representations that impact all members of a corresponding group. Here we assess whether such social-emotional consequences of motor-response action versus inaction also operate on item-level representations of specific individuals.

Response inhibition immediately elicits negative affect and devalues associated stimuli: Evidence from facial electromyography.

Response inhibition negatively impacts the emotional and motivational significance of associated stimuli. Current accounts question whether this stimulus devaluation effect occurs immediately via negative affect elicited by inhibition, or only occurs later via a misattribution of decreased fluency as unpleasantness in the context of an explicit affective-evaluation task. Using facial electromyography, we recorded indirect physiological markers of affective response during a response-inhibition (Go/No-go) task to test opposing predictions arising from the immediate-affect and delayed-misattribution hypotheses.

Physiological and cognitive measures during prolonged sitting: Comparisons between a standard and multi-axial office chair.

Prolonged sitting, common in many workplaces, reduces blood flow to the lower limb and has negative health outcomes. CoreChair is an active-sitting chair that encourages increased movement to help mitigate these outcomes. Physiological and cognitive measures were recorded in ten subjects over 4 h of sitting in both the CoreChair and a traditional office chair.

Cognitive-behavioral and electrophysiological evidence of the affective consequences of ignoring stimulus representations in working memory.

Ignoring visual stimuli in the external environment leads to decreased liking of those items, a phenomenon attributed to the affective consequences of attentional inhibition. Here we investigated the generality of this "distractor devaluation" phenomenon by asking whether ignoring stimuli represented internally within visual working memory has the same affective consequences. In two experiments we presented participants with two or three visual stimuli and then, after the stimuli were no longer visible, provided an attentional cue indicating which item in memory was the target they would have to later recall, and which were task-irrelevant distractors.

Less approach, more avoidance: Response inhibition has motivational consequences for sexual stimuli that reflect changes in affective value not a lingering global brake on behavior.

Response inhibition negatively impacts subsequent hedonic evaluations of motivationally relevant stimuli and reduces the behavioral incentive to seek and obtain such items. Here we expand the investigation of the motivational consequences of inhibition by presenting sexually appealing and nonappealing images in a go/no-go task and a subsequent image-viewing task. Each initially obscured image in the viewing task could either be made more visible or less visible by repeatedly pressing different keys.

Neural evidence that inhibition is linked to the affective devaluation of distractors that match the contents of working memory.

Stimuli appearing as visual distractors subsequently receive more negative affective evaluations than novel items or prior targets of attention. Leading accounts question whether this distractor devaluation effect occurs through evaluative codes that become associated with distractors as a mere artefact of attention-task instructions, or through affective consequences of attentional inhibition when applied to prevent distractor interference. Here we test opposing predictions arising from the evaluative-coding and devaluation-by-inhibition hypotheses using an electrophysiological marker of attentional inhibition in a task that requires participants to avoid interference from abstract-shape distractors presented while maintaining a uniquely-colored stimulus in memory.

Suppressing memories of words and familiar objects results in their affective devaluation: Evidence from Think/No-think tasks.

Potentially distracting or otherwise-inappropriate stimuli, thoughts, or actions often must be inhibited to prevent interference with goal-directed behaviour. Growing evidence suggests that the impact of inhibition is not limited to reduced neurocognitive processing, but also includes negative affective consequences for any associated stimuli. The link between inhibition and aversive response has primarily been studied using tasks involving attentional- or response-related inhibition of external sensory stimuli.

To be spurned no more: The affective and behavioral consequences of social and nonsocial rejection.

Social pain is often associated with social rejection and shares neural correlates with the bothersome aspect of physical pain, which may also indicate an overlap in function. Pain has been described as a motivational signal to respond to the source of the pain in an adaptive way, such as by altering behavior. We tested whether social pain causes similarly adaptive alterations in behavior.

Stimulus-category competition, inhibition, and affective devaluation: a novel account of the uncanny valley.

Stimuli that resemble humans, but are not perfectly human-like, are disliked compared to distinctly human and non-human stimuli. Accounts of this "Uncanny Valley" effect often focus on how changes in human resemblance can evoke different emotional responses. We present an alternate account based on the novel hypothesis that the Uncanny Valley is not directly related to 'human-likeness' per se, but instead reflects a more general form of stimulus devaluation that occurs when inhibition is triggered to resolve conflict between competing stimulus-related representations.

Hot or not: response inhibition reduces the hedonic value and motivational incentive of sexual stimuli.

The motivational incentive of reward-related stimuli can become so salient that it drives behavior at the cost of other needs. Here we show that response inhibition applied during a Go/No-go task not only impacts hedonic evaluations but also reduces the behavioral incentive of motivationally relevant stimuli. We first examined the impact of response inhibition on the hedonic value of sex stimuli associated with strong behavioral-approach responses (Experiment 1).

The Unengaged Mind: Defining Boredom in Terms of Attention.

Our central goal is to provide a definition of boredom in terms of the underlying mental processes that occur during an instance of boredom. Through the synthesis of psychodynamic, existential, arousal, and cognitive theories of boredom, we argue that boredom is universally conceptualized as "the aversive experience of wanting, but being unable, to engage in satisfying activity." We propose to map this conceptualization onto underlying mental processes.

The affective consequences of cognitive inhibition: devaluation or neutralization?

Affective evaluations of previously ignored visual stimuli are more negative than those of novel items or prior targets of attention or response. This has been taken as evidence that inhibition has negative affective consequences. But inhibition could act instead to attenuate or "neutralize" preexisting affective salience, predicting opposite effects for stimuli that were initially positive or negative in valence.

Manipulations of attention enhance self-regulation.

Successful goal-directed behavior requires self-regulation to override competing impulses. Emerging evidence suggests that attention may mediate such acts, but little is known about the specific operations through which attention might influence self-regulation. Here we test this often-implicit assumption by manipulating attention mechanisms in two ways: one controlling the inhibition of inappropriate responses; the other controlling the breadth of attention.

The units of thought.

That associative processing provides the vehicle of thought is a long-standing idea. We describe here observations from cognitive neuroimaging that elucidate the neural processing that mediates this element. This account further allows a more specific ascription of a cognitive function to the brain's "default" activity in mindwandering.

Top-down facilitation of visual object recognition: object-based and context-based contributions.

The neural mechanisms subserving visual recognition are traditionally described in terms of bottom-up analysis, whereby increasingly complex aspects of the visual input are processed along a hierarchical progression of cortical regions. However, the importance of top-down facilitation in successful recognition has been emphasized in recent models and research findings. Here we consider evidence for top-down facilitation of recognition that is triggered by early information about an object, as well as by contextual associations between an object and other objects with which it typically appears.

Affective evaluations of objects are influenced by observed gaze direction and emotional expression.

Gaze direction signals another person's focus of interest. Facial expressions convey information about their mental state. Appropriate responses to these signals should reflect their combined influence, yet current evidence suggests that gaze-cueing effects for objects near an observed face are not modulated by its emotional expression.

Emotional devaluation of distracting patterns and faces: a consequence of attentional inhibition during visual search?

Visual search has been studied extensively, yet little is known about how its constituent processes affect subsequent emotional evaluation of searched-for and searched-through items. In 3 experiments, the authors asked observers to locate a colored pattern or tinted face in an array of other patterns or faces. Shortly thereafter, either the target or a distractor was rated on an emotional scale (patterns, cheerfulness; faces, trustworthiness).

Attentional inhibition has social-emotional consequences for unfamiliar faces.

Visual attention studies often rely on response time measures to show the impact of attentional facilitation and inhibition. Here we extend the investigation of the effects of attention on behavior and show that prior attentional states associated with unfamiliar faces can influence subsequent social-emotional judgments about those faces. Participants were shown pairs of face images and were asked to withhold a response if a transparent stop-signal cue appeared over one of the faces.

The affective consequences of visual attention in preview search.

Comparisons of emotional evaluations of abstract stimuli just seen in a two-object visual search task show that prior distractors are devalued, as compared with prior targets or novel items, perhaps as a consequence of persistent attentional inhibition (Raymond, Fenske, & Tavassoli, 2003). To further explore such attention-emotion effects, we measured search response time in a preview search task and emotional evaluations of colorful, complex images just seen therein. On preview trials, the distractors appeared 1,000 msec before the remaining items.

The rise and fall of priming: how visual exposure shapes cortical representations of objects.

How does the amount of time for which we see an object influence the nature and content of its cortical representation? To address this question, we varied the duration of initial exposure to visual objects and then measured functional magnetic resonance imaging (fMRI) signal and behavioral performance during a subsequent repeated presentation of these objects. We report a novel 'rise-and-fall' pattern relating exposure duration and the corresponding magnitude of fMRI cortical signal. Compared with novel objects, repeated objects elicited maximal cortical response reduction when initially presented for 250 ms.

Modulation of focused attention by faces expressing emotion: evidence from flanker tasks.

Three experiments evaluated whether facial expression can modulate the allocation of focused attention. Identification of emotionally expressive target faces was typically faster when they were flanked by identical (compatible) faces compared with when they were flanked by different (incompatible) faces. This flanker compatibility effect was significantly smaller when target faces expressed negative compared with positive emotion (see Experiment 1A); however, when the faces were altered to disrupt emotional expression, yet retain feature differences, equal flanker compatibility effects were observed (see Experiment 1B).

Selective attention determines emotional responses to novel visual stimuli.

Distinct complex brain systems support selective attention and emotion, but connections between them suggest that human behavior should reflect reciprocal interactions of these systems. Although there is ample evidence that emotional stimuli modulate attentional processes, it is not known whether attention influences emotional behavior. Here we show that evaluation of the emotional tone (cheery/dreary) of complex but meaningless visual patterns can be modulated by the prior attentional state (attending vs.
