Bird communities across different levels of human settlement: A comparative analysis from two northern Amazonian ecoregions.

Urban ecosystems are increasingly dominating landscapes globally, so it is critical to understand the effects of human settlements on biodiversity. Bird communities are effective indicators because they are impacted by the size and expansion of human settlements, exemplified by changes in their habitat use, breeding and foraging behaviours, as well as patterns of richness and abundance. Existing studies on bird community responses to human settlements have mainly focused on single ecoregions and large cities, leaving a gap in comparative research on how differently sized human settlements affect bird communities across various ecoregions.

Effects of blocked versus interleaved training on relative value learning.

In reinforcement learning tasks, people learn the values of options relative to other options in the local context. Prior research suggests that relative value learning is enhanced when choice contexts are temporally clustered in a blocked sequence compared to a randomly interleaved sequence. The present study was aimed at further investigating the effects of blocked versus interleaved training using a choice task that distinguishes among different contextual encoding models.

The effect of auditory valence on subsequent visual semantic processing.

Emotion influences many cognitive processes and plays an important role in our daily life. Previous studies focused on the effects of arousal on subsequent cognitive processing, but the effect of valence on subsequent semantic processing is still not clear. The present study examined the effect of auditory valence on subsequent visual semantic processing when controlling for arousal.

Testing models of context-dependent outcome encoding in reinforcement learning.

Previous studies of reinforcement learning (RL) have established that choice outcomes are encoded in a context-dependent fashion. Several computational models have been proposed to explain context-dependent encoding, including reference point centering and range adaptation models. The former assumes that outcomes are centered around a running estimate of the average reward in each choice context, while the latter assumes that outcomes are compared to the minimum reward and then scaled by an estimate of the range of outcomes in each choice context.

Reinforcement learning in and out of context: The effects of attentional focus.

In reinforcement learning (RL) tasks, decision makers learn the values of actions in a context-dependent fashion. Although context dependence has many advantages, it can lead to suboptimal preferences when choice options are extrapolated beyond their original encoding contexts. Here, we tested whether we could manipulate context dependence in RL by introducing a secondary task designed to bias attention toward either absolute or relative outcomes.

Context effects on choice under cognitive load.

The context-dependent nature of choice is well illustrated by decoy effects, in which adding an alternative to a choice set can change the preference relations among the other alternatives. The current within-subjects study tested whether manipulating cognitive load affects the magnitude of attraction and compromise decoy effects. Participants (n = 96) made simulated online grocery shopping choices from three options described by price and quality for each grocery item they encountered.

Bird diversity and psychological wellbeing: A comparison of green and coastal blue space in a neotropical city.

Accelerating rates of urbanisation are contributing to biodiversity declines worldwide. However, urban green (e.g.

Perceived biodiversity, sound, naturalness and safety enhance the restorative quality and wellbeing benefits of green and blue space in a neotropical city.

Urban land cover expansion and human population growth are accelerating worldwide. This is resulting in the loss and degradation of green and blue spaces (e.g.

Autonomic responses to choice outcomes: Links to task performance and reinforcement-learning parameters.

Previous work has shown that autonomic responses to choice feedback can predict subsequent decision-making. In this study, we tested whether skin conductance responses (SCRs) and heart rate (HR) decelerations following the presentation of choice outcomes predict Iowa Gambling Task performance in nonclinical participants (n = 64). We also examined how these signals related to parameters of a reinforcement-learning (RL) model.

Context effects on reproduced magnitudes from short-term and long-term memory.

Extant research has demonstrated strong contextual dependencies in reproducing magnitudes of perceptual stimuli from short-term memory. Two experiments examined how context as defined by (a) the mean of the distribution, (b) stimulus ranks, (c) values of anchor stimuli used in the reproduction task, and (d) values from the most recent trial operate on estimates of square size. Experiment 1 demonstrated distributional contrast effects on ratings of squares and distributional assimilation effects on reproduction of squares from short-term memory for the same participants.

Context effects in reproduction and perception of song tempo.

Studies of tempo perception suggest that exposure to a distribution of predominantly faster or slower versions of a song can shift one's memory for the original tempo toward the contextual tempos. Three experiments were conducted to examine whether similar assimilation effects would occur when participants are asked to reproduce the tempo of a song from memory. In Experiments 1 and 2, participants listened to a tempo-altered version of a pop song prior to tapping out the original tempo from memory on each trial.
