New students' psychological well‐being and its relation to first year academic performance in a UK university

Aims: This study (1) profiled the well‐being of first year students entering one UK university, and (2) explored whether initial well‐being and year end academic performance were correlated. Method: A total of 117 students (mean age 21, 67% female) completed the Rosenberg Self‐Esteem Scale, Clinical Outcomes in Routine Evaluation‐General Population, and Liebowitz Social Anxiety Scale; academic achievement data were collected from academic records. Results: Almost a quarter of the sample reported quasi‐clinical levels of psychological distress and moderate to very severe social anxiety. Quasi‐clinical levels of psychological distress were associated with low self‐esteem and social anxiety. No statistically significant links were found between well‐being as assessed at the beginning of the first year and academic achievement at the end of the first year. Discussion: The failure to find a link in this study between initial well‐being and academic performance at the end of the first year suggests that further investigation is required to understand how academic achievement is related to student well‐being.     

Salivary Cortisol as a Biomarker in Social Science Research

Cortisol, a neuroendocrine hormone measurable in saliva, responds to internal and external triggers. In providing a peripheral ‘window on the brain’, it has been increasingly incorporated into social psychological studies. Cortisol secretion can be studied in two main ways, examination of acute stress reactivity and examination of the basal circadian patterns. These can inform aspects of acute and chronic stress exposure and relationships with health. Within non‐clinical populations, cortisol effects are largely driven by differences in the perception of threat. For social psychologists, this provides an interesting avenue for the investigation of social factors that mediate perceptions of threat, such as social support, relationship processes, and group dynamics in acute and chronic stress. This paper provides a background to understanding the regulation and function of cortisol, and issues arising in relation to its measurement in saliva. It discusses and makes recommendations on the use of appropriate cortisol measures in the study of both acute and chronic stress. Used and interpreted appropriately, stress reactivity and basal ambulatory measures of salivary cortisol can provide a valuable adjunct to self‐report and observation in social psychological research. © 2013 John Wiley & Sons Ltd     

Within-subject testing of the signaled-reinforcement effect on operant responding as measured by response rate and resistance to change

Response rates under random-interval schedules are lower when a brief (500 ms) signal accompanies reinforcement than when there is no signal. The present study examined this signaled-reinforcement effect and its relation to resistance to change. In Experiment 1, rats responded on a multiple random-interval 60-s random-interval 60-s schedule, with signaled reinforcement in only one component. Response resistance to alternative reinforcement, prefeeding, and extinction was compared between these components. Lower response rates, and greater resistance to change, occurred in the component with the reinforcement signal. In Experiment 2, response rates and resistance to change were compared after training on a multiple random-interval 60-s random-interval 60-s schedule in which reinforcer delivery was unsignaled in one component and a response-produced uncorrelated stimulus was presented in the other component. Higher response rates and greater resistance to change occurred with the uncorrelated stimulus. These results highlight the significance of considering the effects of an uncorrelated signal when used as a control condition, and challenge accounts of resistance to change that depend solely on reinforcer rate.     

The relative importance of responses to S+ and S- in simultaneous discrimination learning

Earlier research indicated that errors were more important in discrimination learning than correct responses (the Moss-Harlow effect). This conclusion was based on a variety of experimental designs each of which had basic methodological problems, usually involving novelty or order effects. A circular apparatus which allowed the simultaneous presentation of several different stimuli was used to study discrimination learning with S + and S - differentially weighted. It was found that variability in S - was more detrimental to discrimination learning than variability in S + although this finding depended on the presence of a constant stimulus. The results were interpreted as supporting the proposition that in discrimination learning rats learn more to avoid S- than to approach S+.     

Investigating behavior inhibition in obsessive-compulsive disorder: Evidence from eye movements

We investigated the role of inhibition failure in Obsessive Compulsive Disorder (OCD) through an eye tracking experiment. Twenty-five subjects with OCD were recruited, as well as 25 with Generalized Anxiety Disorder (GAD) and 25 healthy controls. A 3 (group: OCD group, GAD group and control group) × 2 (target eccentricity: far and near) × 2 (saccade task: prosaccade and antisaccade) mixed design was used, with all participants completing two sets of tasks involving both prosaccade (eye movement towards a target) and antisaccade (eye movement away from a target). The main outcome was the eye movement index, including the saccade latency (the time interval from the onset of the target screen to the first saccade) and the error rate of saccade direction. The antisaccade latency and antisaccade error rates for OCDs were much higher than those for GADs and healthy controls. OCDs had longer latency and error rates for antisaccades than for prosaccades, and for far-eccentricity rather than near-eccentricity stimuli. These results suggest that OCDs experience difficulty with behavior inhibition, and that they have higher visual sensitivity to peripheral stimuli. In particular, they show greatest difficulty in inhibiting behavior directed towards peripheral stimuli.     

Characterizing the ADHD phenotype for genetic studies

The genetic study of ADHD has made considerable progress. Further developments in the field will be reliant in part on identifying the most appropriate phenotypes for genetic analysis. The use of both categorical and dimensional measures of symptoms related to ADHD has been productive. The use of multiple reporters is a valuable feature of the characterization of psychopathology in children. It is argued that the use of aggregated measures to characterize the ADHD phenotype, particularly to establish its pervasiveness, is desirable. The recognition of the multiple comorbidities of ADHD can help to isolate more specific genetic influences. In relation to both reading disability and conduct disorder there is evidence that genes may be involved in the comorbid condition that are different from pure ADHD. To date, progress with the investigation of endophenotypes for ADHD has been disappointing. It is suggested that extending such studies beyond cognitive underpinnings to include physiological and metabolic markers might facilitate progress.     

A critique of science and R&D-based models of endogenous growth

Conclusion We have argued against the conventional treatment of science from two directions: firstly, we show that its assumptions about the mechanics of technology transfer are at odds with what occurs in practice. Secondly, the predictions of models based on conventional assumptions receive little support empirically, and are on some occasions contradicted by the data. We believe that the weaknesses we have discussed prompt a re-analysis of science as the workings of invisible colleges. Moreover, we note that there appears, at present, to be no empirical or sound theoretical reason to suppose that, for reasons of economic growth, governments need fund science. the author of The Economic Laws of Scientific Research, Macmillan/St Martin’s Press, 1996.     

The Effects of Sad Mood on Reports of Parents’ Caregiving Behaviors

Two studies examined the hypothesis that recollections of parents’ child-rearing behaviors on the Parental Bonding Instrument (PBI: Parker, Tupling, & Brown, 1979) are influenced by current mood. Study 1 investigated the effects of sad versus neutral mood induction on PBI scores in 50 college students. Participants rated their parents as less caring following the sad mood induction than following the neutral induction. Study 2 investigated the effects of naturally occurring changes in depressive symptoms on PBI scores over a two month period. Changes in depressive symptoms correlated with changes in father care scores and tended to correlate with changes in mother care scores. Findings from both studies suggest that retrospective reports of parenting are susceptible to mood bias and highlight the limits of using cross sectional designs to explore the relationship between parenting and depression.     

Interference with judgments of control and attentional shift as a result of prior exposure to controllable and uncontrollable feedback

The experiment was carried out to determine whether exposure to an uncontrollable relationship between an action and its outcome during a non-aversive pretreatment phase would affect subsequent ratings of perceived control emitted by human participants. Its other aim was to investigate the effect of such pre-exposure on the attentional focus of humans on internal and external cues. Participants were assigned to one of three groups; an uncontrollable pretreatment, a controllable pretreatment, and no pretreatment. Participants exposed to uncontrollable outcomes (unsolvable problems) gave lower ratings of control over a produced outcome than the other two groups, indicating the interference with subsequent judgments of control. The exposure to uncontrollable outcomes also increased levels of distraction produced by an external cue in a reaction time experiment. Such an effect was not found in the groups who had not been exposed to uncontrollable outcomes. These dual effects are similar to those noted in non-humans subjected to uncontrollable outcomes.     

A reanalysis of the CARIN theory of conceptual combination

The competition among relations in nominals (CARIN) theory of conceptual combination (C. L. Gagné & E. J. Shoben, 1997) proposes that people interpret nominal compounds by selecting a relation from a pool of competing alternatives and that relation availability is influenced by the frequency with which relations have been previously associated with the modifying concept. The current authors derived relation frequencies by using a sample of compounds occurring in the British National Corpus and compared them with those derived by Gagné and Shoben. The authors demonstrated that the original relation frequencies are unrepresentative and that Gagne' and Shoben's technique for dichotomizing them into high and low is unreliable. In addition, the authors revealed anomalies in the mathematical instantiation of the CARIN model and showed that it does not provide evidence for competition among relations.
