Implicit attitudes towards meat and vegetables in vegetarians and nonvegetarians

Previous research, in which self‐report measures were used, showed that vegetarians have more negative beliefs about meat than nonvegetarians. An important limitation of this research is that it did not examine differences in spontaneous affective reactions (i.e., implicit attitudes) towards meat and other types of food. We therefore conducted a new study in which not only self‐report measures were used, but also two tasks that have been developed to measure implicit attitudes: The Implicit Association Test (IAT) and a pictorial version of the Extrinsic Affective Simon Task (EAST). Both the IAT and EAST revealed that implicit attitudes towards vegetables (as compared to implicit attitudes towards meat) were more positive in vegetarians than in nonvegetarians. In line with previous findings, the self‐report measures showed that, compared to nonvegetarians, vegetarians had more positive attitudes towards vegetables and more negative attitudes towards meat. The IAT and EAST measures both correlated in the expected manner with self‐reported attitudes. A logistic regression showed that self‐reported attitudes were an almost perfect predictor of group status (vegetarian or nonvegetarian), and that adding the IAT and EAST measures as predictors did not improve prediction of group status. The results suggest that vegetarians and nonvegetarians differ in their spontaneous affective reaction towards vegetables or meat, and provide further evidence for the validity of the IAT and EAST as measures of inter‐individual differences in attitudes. Implicit attitudes could influence eating behaviour indirectly by biasing the decision to become a vegetarian or by determining how difficult it is for someone to maintain a vegetarian diet.     

Rolipram reverses scopolamine-induced and time-dependent memory deficits in object recognition by different mechanisms of action

In this study, the effect of the selective phosphodiesterase type 4 (PDE4) inhibitor rolipram on memory performance was investigated using the object recognition task. First, three doses of rolipram (0.01, 0.03 or 0.1 mg/kg) were tested with a 24h delay between the learning (T1) and the test (T2) trial. Doses of rolipram were injected at different time points (30 min before T1, immediately after T1 or 3 h after T1). In a second experiment, the effects of rolipram (0.03, 0.1 or 0.3 mg/kg) were tested in combination with scopolamine (0.1 mg/kg) applying a 1 h delay between trials. Both substances were administered 30 min before T1. Using a 24h interval, rolipram showed an improvement in long-term memory performance when injected 3 h after T1 at a dose of 0.03 mg/kg. Further, rolipram reversed the scopolamine-induced short-term memory deficit at a dose of 0.1 mg/kg. Although the improved memory performance in both conditions is likely to be explained by elevated cAMP levels, two separate working mechanisms might explain these effects.     

The Props are Falling Down and We Want to Make Music: A Narrative Perspective on Organisations in Transition (Violins/Violence in Organisations)

While South African society finds itself in the throes of political changes, therapists working within organisations in transition find themselves challenged by the turbulence of transformation. The authors are a group of therapists attempting to understand, from a narrative perspective, the organisational context within which they work. This paper recounts the processes around the design, implementation, and outcomes of a workshop on this theme. The main body of the paper consists of a letter that was sent to participants after the workshop. The reader is invited to join collaboratively in our reflections so as to continue an open-ended, creative process.     

The contribution of working memory resources in the verification of simple mental arithmetic sums

The present study replicated the investigations of Lemaire, Abdi, and Fayol with some modifications: the random time interval generation (RIG) task was used and the stimuli were created in another way. The results provide additional evidence for the crucial role of the central executive in the speed of solving both true and false sums and for the role of the phonological loop in solving false sums. However, the findings concerning the role of this slave system in solving true sums were different. Possible explanations and limitations of these results are discussed.

Judging risk behaviour and risk preference: The role of the evaluative connotation of risk terms

Two experiments investigate the impact of the evaluative connotation of risk terms on the judgment of risk behaviour and on risk preference. In the first experiment we focus on (1) the evaluation congruence of the risk terms with a general risk norm and (2) with subjects' individual risk preference, and its effects on the extremity of judgments of risk behaviour. In the second experiment we address (3) the effects of evaluative connotation of risk terms on risk preference. In the first experiment subjects were presented with four decision problems, each with a risky and a cautious decision option, and were required to judge options. Results showed that the judged discrepancy between the risky and cautious option was larger on scales which were evaluatively congruent with the general risk norm for that specific decision problem or with subjects' individual preference. More specificly, in decision problems for which there was considerable consensus about the risk-norm judgments were more extreme on scales which were congruent with the risk norm, in those problems lacking a clear-cut risk-norm judgments were more extreme on scales congruent with subjects' individual risk preference. In the second experiment we studied the reverse relation between the evaluative connotation of risk terms and risk preference. This experiment demonstrates that using evaluatively biased risk terms can affect risk preference. Using terms which imply a positive evaluation of risk-taking and a negative evaluation of risk avoidance led to increased risk preference, and vice versa. Results are discussed in the context of accentuation theory.     

Does negative mood influence self-report assessment of individual and relational measures? An experimental analysis

The present study was designed to test the influence of negative mood on the self-report of individual and relational correlates of depression and marital distress. The authors applied a combined experimental mood induction procedure, based on music, autobiographical recall, and environmental manipulation. Results showed that the mood manipulation was effective, and the depressed Mood Induction Procedure (MIP) and neutral MIP groups did not differ in their self-rated measures of the above-mentioned variables. In conclusion, the authors argue that these measures are generally insensitive to depressed mood, providing an important contribution to this literature.     

Unhindered Spatial Processing During Route Memorization is Required to Maximize Both Spatial and Verbal Route Knowledge

To successfully remember a route in a physical environment, individuals are believed to process and store both verbal and spatial information of that route. The present study tested whether both spatial and verbal contents are necessary to form an effective route memory. For that purpose, route learning was performed in three concurrent task conditions (spatial, verbal and control) and appraised at two moments in time, via three route memory tests (spatial, verbal and spatial–verbal). Results showed that route memory generally improved across time and that spatial information was remembered better than verbal information. The concurrent spatial condition resulted in lower retention scores of both spatial and verbal route knowledge. These results suggest that effective spatial processing forms a scaffold without which long‐term retention lacks detail of both spatial and verbal route knowledge. It is discussed how these findings add to understanding spatial memory of routes. Copyright © 2013 John Wiley & Sons, Ltd.     

The psychometric properties of the Recovery Experiences Questionnaire of employees in a higher education institution

The objective of this study was to investigate the factorial validity and reliability of scores from the Recovery Experience Questionnaire (REQ) in a higher education institution. As part of the measure validation, the relationships of the four recovery dimensions (psychological detachment, relaxation, mastery and control) to other variables in the nomological network (work-home interference, home-work interference and ill health) were investigated. Data was collected from 366 participants (females = 65.3%; white = 80.35%). Confirmatory factor analysis was used to test competing factorial models. The results supported a four-factor structure for the REQ. Relationships with other variables in the nomological network were all theoretically consistent, as expected.     

Are phonological influences on lexical (mis)selection the result of a monitoring bias?

A monitoring bias account is often used to explain speech error patterns that seem to be the result of an interactive language production system, like phonological influences on lexical selection errors. A biased monitor is suggested to detect and covertly correct certain errors more often than others. For instance, this account predicts that errors that are phonologically similar to intended words are harder to detect than those that are phonologically dissimilar. To test this, we tried to elicit phonological errors under the same conditions as those that show other kinds of lexical selection errors. In five experiments, we presented participants with high cloze probability sentence fragments followed by a picture that was semantically related, a homophone of a semantically related word, or phonologically related to the (implicit) last word of the sentence. All experiments elicited semantic completions or homophones of semantic completions, but none elicited phonological completions. This finding is hard to reconcile with a monitoring bias account and is better explained with an interactive production system. Additionally, this finding constrains the amount of bottom-up information flow in interactive models.     

Delinquent Development in Dutch Childhood Arrestees: Developmental Trajectories,Risk Factors and Co-morbidity with Adverse Outcomes during Adolescence

Heterogeneity of re-offending patterns was studied in a group of 287 male early onset offenders who were first arrested before age 12. By combining data on the frequency and severity of offending as registered by the police over a 5-year follow-up period, three delinquent trajectories were identified; low, escalating, and high level re-offenders. Predicting group membership by individual and environmental characteristics known to the police at the time of the first arrest proved difficult. Compared to low level re-offenders, escalators were older and more often came from disadvantaged neighborhoods. High level re-offenders were also older at onset, more often had a non-Western ethnic background, and initially committed more vandalism. Furthermore, at the first police encounter, the police reacted more severely towards those who later became high level re-offenders. Finally, high and escalating re-offenders more often had other adverse outcomes, such as criminal victimization and Child Welfare Agency involvement.
