“Watch out!”: Effects of instructed threat and avoidance on human free‐operant approach–avoidance behavior

Approach–avoidance paradigms create a competition between appetitive and aversive contingencies and are widely used in nonhuman research on anxiety. Here, we examined how instructions about threat and avoidance impact control by competing contingencies over human approach–avoidance behavior. Additionally, Experiment 1 examined the effects of threat magnitude (money loss amount) and avoidance cost (fixed ratio requirements), whereas Experiment 2 examined the effects of threat information (available, unavailable and inaccurate) on approach–avoidance. During the task, approach responding was modeled by reinforcing responding with money on a FR schedule. By performing an observing response, participants produced an escalating “threat meter”. Instructions stated that the threat meter levels displayed the current probability of losing money, when in fact loss only occurred when the level reached the maximum. Instructions also stated pressing an avoidance button lowered the threat level. Overall, instructions produced cycles of approach and avoidance responding with transitions from approach to avoidance when threat was high and transitions back to approach after avoidance reduced threat. Experiment 1 revealed increasing avoidance cost, but not threat magnitude, shifted approach–avoidance transitions to higher threat levels and increased anxiety ratings, but did not influence the frequency of approach–avoidance cycles. Experiment 2 revealed when threat level information was available or absent earnings were high, but earnings decreased when inaccurate threat information was incompatible with contingencies. Our findings build on prior nonhuman and human approach–avoidance research by highlighting how instructed threat and avoidance can impact human AA behavior and self‐reported anxiety.     

Continued Participation in Youth Sports: The Role of Achievement Motivation

This study explored the antecedents of enjoyment and intention to continue in youth sports using the social-cognitive model of achievement motivation with the 2 × 2 achievement goal modification. Participants were 327 sports participants between 11 and 15 years of age. Individuals high in incremental beliefs reported greater enjoyment and intention to continue. This was perhaps due to endorsing mastery-approach goals. Individuals relatively high in entity beliefs reported relatively less enjoyment. This was perhaps due to endorsing performance-avoidance goals. These individuals also reported relatively less intention to continue regardless of their achievement goals. Findings could have implications for preventing dropout from youth sports.     

Anxiety, Demoralization, and the Gender Difference in Job Satisfaction

The tendency for women in Canada and the United States to report being more satisfied than men with their jobs is considered paradoxical because women, on average, receive fewer job-related resources than men. Theory and research suggest that the magnitude of the gender difference that underlies that paradox may increase as levels of negative affect increase. Using data from people living and working in Toronto, Canada, this study evaluates hypotheses about the joint association of gender and two forms of negative affect, anxiety and demoralization, with job satisfaction. Data collected in telephone interviews are analyzed using ordinal probit regression. As job satisfaction decreases with increasing negative affect, the size of the gender difference in job satisfaction increases. When job characteristics indicative of job quality are controlled, the interaction between gender and demoralization is reduced to a non-significant level, but the interaction between gender and anxiety changes little, and remains significant. The results are interpreted as indicating that as negative affect increases, women are more likely to reference standards that counterbalance decreases in their satisfaction (e.g., standards linked to “communion” with co-workers), and men are more likely to reference standards that further decrease their satisfaction (e.g., standards linked to relative advantage). The persistence of the interaction between gender and anxiety after job characteristics are controlled suggests that anxiety-provoking experiences outside of the workplace may contribute to the gender difference in job satisfaction. The associations among quality of work, demoralization, and job satisfaction are stronger among men than women, explaining the interaction of gender with demoralization.     

Delay discounting as emotional processing: An electrophysiological study

Both theoretical models and functional imaging studies implicate the involvement of emotions within the delay discounting process. However, defining this role has been difficult to establish with neuroimaging techniques given the automaticity of emotional responses. To address this, the current study examined electrophysiological correlates involved in the detection and evaluation of immediate and delayed monetary outcomes. Our results showed that modulation of both early and later ERP components previously associated with affective stimuli processing are sensitive to the signalling of delayed rewards. Together with behavioural reaction times that favoured immediacy, we demonstrated, for the first time, that time delays modify the incentive value of monetary rewards via mechanisms of emotional bias and selective visual attention. Furthermore, our data are consistent with the hypothesis that delayed and thus intangible rewards are perceived less saliently, and rely on emotion as a common currency within decision making. This study provides a new approach to delay discounting and highlights a potential novel route through which delay discounting may be investigated.     

‘A Compound Wholly Mortal’: Locke and Newton on the Metaphysics of (Personal) Immortality

In this paper I consider a cluster of positions which depart from the immortalist and dualist anthropologies of Rene Descartes and Henry More. In particular, I argue that John Locke and Isaac Newton are attracted to a monistic mind-body metaphysics, which while resisting neat characterization, occupies a conceptual space distinct from the dualism of the immortalists, on the one hand, and thoroughgoing materialism of Thomas Hobbes, on the other. They propound a sort of property monism: mind and body are distinct, with distinct characteristics and functions, but are, nevertheless, ontologically interdependent. Consciousness – the locus of personhood, and thus, a necessary condition for personal immortality – is an embodied phenomenon; its preservation requires the life and proper functioning of the body. Dying with the dissolution of his body, then, man is a compound wholly mortal. Nevertheless, both Locke and Newton accepted the possibility of personal immortality; with Hobbes, both looked to the Biblical promise of bodily resurrection. For with the re-vitalization of the body – and a subsequent restoration of consciousness and memory – personal identity is preserved, even beyond the grave.     

Mindreading abilities in sexual offenders: an analysis of theory of mind processes

The paper aims to assess the theory of mind (ToM) of sexual offenders. We administered to 21 sexual offenders and to 21 nonoffenders two classical first- and second-order ToM tasks, a selection of six Strange Stories, and a semi-structured interview, the Theory of Mind Assessment Scale (Th.o.m.a.s), which provides a multi-dimensional evaluation of ToM, investigating first- vs. third-person and egocentric vs. allocentric perspectives. Results show that sexual offenders performed worse than controls on second-order ToM tasks, on Strange Stories and on each of the Th.o.m.a.s dimensions, whereas they did as well as the control group on first-order ToM tasks. A detailed analysis of participants’ performance on Th.o.m.a.s. showed that sex offenders performed worse on the third-person than on the first-person ToM scale, and worse on the allocentric than on the egocentric perspective; these findings did not apply to the controls. Implications for future research and treatment are discussed.     

Home background,intelligence, personality and education as predictors of unemployment in young people

This study is concerned with the degree to which youth unemployment in N. Ireland can be predicted from a number of antecedent variables. It was found that home background, IQ, personality, school type and educational attainments all had significant effects on unemployment. The magnitude of the effects and the causal mechanisms through which they operate were analysed by path analysis in terms of the Duncan-Jencks path-analysis model. The results show that the model holds well for N. Ireland; the major difference is that school type (grammar vs secondary modern) plays a greater role in N. Ireland than school differences in the U.S.A. The data are considered from the point of view of the intergenerational cycle of deprivation hypothesis. It was found that using the criteria of father-son and father-daughter correlation for unemployment, the cycle is quite weak in N. Ireland.     

Tracing the time course of picture--word processing

A number of independent lines of research have suggested that semantic and articulatory information become available differentially from pictures and words. The first of the experiments reported here sought to clarify the time course by which information about pictures and words becomes available by considering the pattern of interference generated when incongruent pictures and words are presented simultaneously in a Stroop-like situation. Previous investigators report that picture naming is easily disrupted by the presence of a distracting word but that word naming is relatively immune to interference from an incongruent picture. Under the assumption that information available from a completed process may disrupt an ongoing process, these results suggest that words access articulatory information more rapidly than do pictures. Experiment 1 extended this paradigm by requiring subjects to verify the category of the target stimulus. In accordance with the hypothesis that picture access the semantic code more rapidly than words, there was a reversal in the interference pattern: Word categorization suffered considerable disruption, whereas picture categorization was minimally affected by the presence of an incongruent word. Experiment 2 sought to further test the hypothesis that access to semantic and articulatory codes is different for pictures and words by examining memory for those items following naming or categorization. Categorized words were better recognized than named words, whereas the reverse was true for pictures, a result which suggests that picture naming involves more extensive processing than picture categorization. Experiment 3 replicated this result under conditions in which viewing time was held constant. The last experiment extended the investigation of memory differences to a situation in which subjects were required to generate the superordinate category name. Here, memory for categorized pictures was as good as memory for named pictures. Category generation also influenced memory for words, memory performance being superior to that following a yes--no verification of category membership. These experiments suggest a model of information access whereby pictures access semantic information were readily than name information, with the reverse being true for words. Memory for both pictures and words was a function of the amount of processing required to access a particular type of information as well as the extent of response differentiation necessitated by the task.
