In an attempt to demonstrate possible maladaptive effects resulting from shaping, two Long Evans rats were trained to jump onto a platform, then to extend their noses downward over the edge to a point where, losing their balance, they fell. The results showed how behaviors such as reaching and rearing can be reinforced differentially to bring about completely maladaptive behavior.

Aggression is commonly associated with increased experiences of peer rejection and maladaptive social information processing biases throughout development. Little is known about the neural correlates of peer rejection that might underlie social information processing biases, and whether these neural correlates are common or different across early- and mid-adolescents on a continuum of aggression. Using the Cyberball task, we examined mediofrontal theta (4-7 Hz) event-related EEG spectral power during conditions of explicit and ambiguous social exclusion in 117 participants (57 early adolescents, ages 10-12 years, and 60 mid-adolescents, ages 14-16 years).

Stress plays a significant role in the onset of numerous psychiatric disorders. Depending on individual resilience or stressor's nature, long-term changes to stress in the brain can lead to a wide range of behavioral symptoms, including social withdrawal, feelings of helplessness, and emotional overeating. The brain receptor molecules are key mediators of these processes, translating neuromodulatory signals into neuronal responses or circuit activity changes that ultimately shape behavioral outcomes.

Background: Decision-making processes may play a pivotal role in the etiology and maintenance of specific phobia. However, empirical evidence is limited. This study examined whether decision-making is only impaired in presence of fear-related stimuli or whether general impairments exist but are more pronounced in the presence of fear-related stimuli.

Involuntary autobiographical memories are memories of personal events that come to mind with no preceding retrieval attempts. They have been studied broadly in autobiographical memory for decades and shown to be common and mostly positive in everyday life. Clinical literature has focused on negative intrusive memories of stressful events and tended to neglect other forms of involuntary autobiographical memories.
