Is prospective memory enhanced by cue-action semantic relatedness and enactment at encoding?

Benefits and costs on prospective memory performance, of enactment at encoding and a semantic association between a cue-action word pair, were investigated in two experiments. Findings revealed superior performance for both younger and older adults following enactment, in contrast to verbal encoding, and when cue-action semantic relatedness was high. Although younger adults outperformed older adults, age did not moderate benefits of cue-action relatedness or enactment. Findings from a second experiment revealed that the inclusion of an instruction to perform a prospective memory task led to increments in response latency to items from the ongoing activity in which that task was embedded, relative to latencies when the ongoing task only was performed. However, this task interference 'cost' did not differ as a function of either cue-action relatedness or enactment. We argue that the high number of cue-action pairs employed here influenced meta-cognitive consciousness, hence determining attention allocation, in all experimental conditions.     

On some types of hallucinatory experience

There are types of non-visual hallucinatory experience which occur in the psychoses other than those which have a critical and derogatory content. Wish-fulfilment plays an important part in the formation of the content of these hallucinations. In others, ‘persecutory’ anxiety also occurs. A comparison is made between hallucinatory and dream content. An hypothesis is presented to account for the perceptual quality of these hallucinatory experiences. The therapeutic implications of these considerations concludes this presentation.     

Expectancy bias mediates the link between social anxiety and memory bias for social evaluation

Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.     

Preventative Behavioral Parent Training: A Preliminary Investigation of Strategies for Preventing At-Risk Children From Developing Later Conduct Problems

Children exhibiting conduct problems comprise the largest source of referrals to children's mental health services. The treatment for conduct problems that possesses the greatest amount of empirical support is behavioral parent training. Unfortunately, a cogent approach to the identification of risk factors and prevention of chronic conduct problem display has not been developed. This project was an initial longitudinal assessment examining the merits of preventative behavioral parent training as a primary prevention strategy for at-risk children. Results demonstrated that prevention participants were engaging in normative rates of disruptive behaviors at 6-month follow-up, whereas comparison children showed a behavioral decline over time.     

Transmitting delusional beliefs in a hypnotic model of folie à deux

Folie à deux is the transference of delusional ideas from one ‘primary’ individual to one or more ‘secondary’ individuals (Lasègue & Falret, 1877). However, it is difficult to investigate experimentally because often only one patient is identified as delusional. We investigated whether hypnosis could model the experiences of the secondary in this delusion. Our primary was a confederate, who displayed two delusional beliefs and attempted to transmit them to hypnotised subjects. We manipulated the status of the confederate so that they were portrayed as either “credible” or merely “interesting”. Many high hypnotisable individuals adopted the confederate’s beliefs and confabulated evidence in support of them. Also, subjects who interacted with a credible confederate extended their delusions beyond those displayed by the confederate. We discuss the strengths and limitations of this approach and suggest ways to improve the validity of this model.     

Lay theories of self‐control influence judgments of individuals who have failed at self‐control

Individuals who have failed at self‐control are often the targets of negative social judgments. We suggest that in some circumstances, individual differences in lay theories regarding self‐control may help account for these reactions. Specifically, people may believe that the ability to exert self‐control is either a fixed quantity (entity theory) or a malleable quantity (incremental theory), and these beliefs may influence their social judgments. In the current investigation, we found that whether lay theories of self‐control were measured or manipulated, entity views of self‐control predicted more negative judgments about a target whose self‐control failure was made salient.

Influences of culture and visual context on real-time social categorization

Social categorization is often thought to be based on facial features and immune to visual context. Moreover, East Asians have been argued to attend to context more than Westerners. American and Chinese participants were presented with faces varying along a White-Asian morph continuum either in American, neutral, or Chinese contexts. American contexts made White categorizations more likely, and Chinese contexts made Asian categorizations more likely. Further, the compatibility between facial and contextual cues influenced the directness of participants' hand trajectories en route to selecting a category response. Even when an ultimate response was not biased by context, the trajectory was nevertheless partially attracted to the category response associated with the context. Importantly, such partial attraction effects in hand trajectories revealed that the influence of context began earlier in time for Chinese relative to American participants. Together, the results show that context systematically influences social categorization, sometimes altering categorization responses and other times only temporarily altering the process. Further, the timing of contextual influences differs by culture. The findings highlight the role of contextual and cultural factors in social categorization.
