The influence of multiple trials and computer-mediated communication on collaborative and individual semantic recall

Collaborative inhibition is a phenomenon where collaborating groups experience a decrement in recall when interacting with others. Despite this, collaboration has been found to improve subsequent individual recall. We explore these effects in semantic recall, which is seldom studied in collaborative retrieval. We also examine “parallel CMC”, a synchronous form of computer-mediated communication that has previously been found to improve collaborative recall [Hinds, J. M., & Payne, S. J. (2016). Collaborative inhibition and semantic recall: Improving collaboration through computer-mediated communication. Applied Cognitive Psychology, 30(4), 554–565]. Sixty three triads completed a semantic recall task, which involved generating words beginning with “PO” or “HE” across three recall trials, in one of three retrieval conditions: Individual–Individual–Individual (III), Face-to-face–Face-to-Face–Individual (FFI) and Parallel–Parallel–Individual (PPI). Collaborative inhibition was present across both collaborative conditions. Individual recall in Recall 3 was higher when participants had previously collaborated in comparison to recalling three times individually. There was no difference between face-to-face and parallel CMC recall, however subsidiary analyses of instance repetitions and subjective organisation highlighted differences in group members' approaches to recall in terms of organisation and attention to others' contributions. We discuss the implications of these findings in relation to retrieval strategy disruption.     

Improved representation of metallic bonding in atomistic simulations

Previous use of the Sutton-Chen glue potential to model deformation processes in aluminium showed marked deviation from the results of an ab initio simulation prior to yield. The origin of this problem is identified, and a revised scheme is suggested and tested. It is based on the fact that the atomic volume is a key quantity in the metallic bonding of sp bonded elements, and our idea should therefore have wide applicability to interatomic bonding models. The scheme uses a new approximate but rapidly computable formula for the local atomic volume in an inhomogeneous system.     

A Comparative Analysis of Social Learning and Social Control Theories in the Prediction of College Crime

This research examines the comparative ability of social control and social learning theories to predict crime on a college campus. Data were obtained from self-report surveys from the first wave of a longitudinal study at a liberal arts college in the Mid-Atlantic region. Results from correlation and regression analyses indicate that both social control and social learning components are related to crime and drug use, with the greatest amount of variance explained by models that include elements of both theories. Issues such as the temporal ordering of peer and individual delinquency and the similarity between belief and definitions are discussed.     

Escaping affect: how motivated emotion regulation creates insensitivity to mass suffering

As the number of people in need of help increases, the degree of compassion people feel for them ironically tends to decrease. This phenomenon is termed the collapse of compassion. Some researchers have suggested that this effect happens because emotions are not triggered by aggregates. We provide evidence for an alternative account. People expect the needs of large groups to be potentially overwhelming, and, as a result, they engage in emotion regulation to prevent themselves from experiencing overwhelming levels of emotion. Because groups are more likely than individuals to elicit emotion regulation, people feel less for groups than for individuals. In Experiment 1, participants displayed the collapse of compassion only when they expected to be asked to donate money to the victims. This suggests that the effect is motivated by self-interest. Experiment 2 showed that the collapse of compassion emerged only for people who were skilled at emotion regulation. In Experiment 3, we manipulated emotion regulation. Participants who were told to down-regulate their emotions showed the collapse of compassion, but participants who were told to experience their emotions did not. We examined the time course of these effects using a dynamic rating to measure affective responses in real time. The time course data suggested that participants regulate emotion toward groups proactively, by preventing themselves from ever experiencing as much emotion toward groups as toward individuals. These findings provide initial evidence that motivated emotion regulation drives insensitivity to mass suffering.     

Weapon Bias: Split-Second Decisions and Unintended Stereotyping

ABSTRACT— Race stereotypes can lead people to claim to see a weapon where there is none. Split-second decisions magnify the bias by limiting people's ability to control responses. Such a bias could have important consequences for decision making by police officers and other authorities interacting with racial minorities. The bias requires no intentional racial animus, occurring even for those who are actively trying to avoid it. This research thus raises difficult questions about intent and responsibility for racially biased errors.     

The effects of experimentally induced stress on false recognition.

The fallibility of memory has become an issue of considerable practical and theoretical importance. Here we studied the impact of experimentally induced stress on the ability of human participants to accurately recognise words presented on a list. We found that stress selectively disrupted participants' ability to distinguish words that were presented for study from critical lure words that were semantically related, but not presented for study. This finding indicates that stress, possibly through its impact on the hippocampus and prefrontal cortex, can potentiate false memories.     

The experience of counselling for female clients with anorexia nervosa: A person‐centred perspective

Anorexia nervosa is a serious and potentially life‐threatening condition, which has been studied from a range of theoretical perspectives. However, the relevance of person‐centred theory and practice in relation to anorexia nervosa has not previously been explored in the literature. The purpose of this study was to understand the experiences of clients who had received counselling for anorexia nervosa, and to set these experiences against the backdrop of person‐centred theory. The study is based on intensive heuristic analysis of interviews with five clients who had completed counselling for anorexia nervosa within the previous three months. Collaboration between the researcher and the participants led to an identification of two of the six ‘core’ conditions identified by Rogers as being of real importance to clients with anorexia: unconditional positive regard and congruence. The context in which counselling is offered was also of crucial significance to these clients. Implications for practice are discussed.     

Prejudice and perception: the role of automatic and controlled processes in misperceiving a weapon

Two experiments used a priming paradigm to investigate the influence of racial cues on the perceptual identification of weapons. In Experiment 1, participants identified guns faster when primed with Black faces compared with White faces. In Experiment 2, participants were required to respond quickly, causing the racial bias to shift from reaction time to accuracy. Participants misidentified tools as guns more often when primed with a Black face than with a White face. L. L. Jacoby's (1991) process dissociation procedure was applied to demonstrate that racial primes influenced automatic (A) processing, but not controlled (C) processing. The response deadline reduced the C estimate but not the A estimate. The motivation to control prejudice moderated the relationship between explicit prejudice and automatic bias. Implications are discussed on applied and theoretical levels.
