Spatial behavior in male and female crayfish (Orconectes rusticus): learning strategies and memory duration

Previous studies have demonstrated that animals use multiple strategies to solve spatial tasks. We used a T-maze to examine spatial behavior in crayfish, using visual and tactile stimuli as place cues and a food-scented escape tank as reinforcement to leave the maze. In trials on a single day and across multiple days, crayfish learned to exit the maze with significantly reduced latency and with fewer turns. In addition, we examined place memory in 40-min periods with the maze closed and found that crayfish spent longer in the vicinity of a previously open exit compared to a closed exit. Probe tests were conducted using a forced-choice procedure to determine whether crayfish remembered the route out of the maze using primarily place cues or response learning. We found that approximately equal numbers of animals used each strategy, and individuals were able to switch from one strategy to the other on different test days. Males and females did not differ significantly in their performance in the place memory test, maze exit task, or probe tests. Both sexes displayed place memory for the exit location and reduced latency to exit during trials 24 h, 48 h, 72 h, and 1 week after initial training trials, suggesting that spatial memories in crayfish are relatively enduring.     

Psychological and criminological factors associated with desistance from violence: A review of the literature

Ample evidence exists that offenders eventually terminate their criminal careers, and this holds true for violent offenders. The causal mechanisms responsible for triggering and maintaining this process remain unclear; meaning that desistance from violence is poorly understood. This comprehensive review of the literature revealed that research in this area is hampered by definitional, operational, and measurement inconsistencies. Several of the conceptual frameworks used to explain desistance from delinquency have not been specifically applied in relation to violence. However, it was found that criminological enquiry suggests that informal social control (e.g., stable relationship and employment) play a role in desistance from violence and that theoretical frameworks which examine both internal and external change seem to show promise as an aid to understanding the desistance process. Psychological research has tended to focus on the role of risk and protective factors in relation to desistance but this, particularly protective factors, is currently under-researched. More knowledge needs to be assembled about how: (1) the mechanics of protective factors mitigate risk of future violence, and (2) how they play a role in the maintenance of violent free behaviors. Findings from criminology and psychology need to be expanded and integrated to extend our understanding of desistance from violence.     

The impact of interpersonal affective relationships and awareness on expertise seeking: A multilevel network investigation

Transactive memory theory suggests that general awareness of expertise location in a group is sufficient to predict expertise seeking. Yet expertise seeking is, at least in part, a social phenomenon between two individuals embedded in a network of social relationships. Taking a multilevel, network perspective, we examined the interplay of affective relationships and awareness on expertise seeking in groups. Hypotheses were tested using network data collected from 693 employees in 53 sales groups. HLM analysis results indicated that awareness of expertise distribution positively influenced the decision to seek expertise at all levels of analysis examined. In addition, both positive and negative affective relationships influenced expertise seeking, although their pattern of influence differed across different levels of analysis. More specifically, having either a positive or a negative affective relationship with another group member affected the decision to seek expertise from that person. Although having many positive relationships had a positive effect on expertise seeking, having many negative affective relationships had no effect. Moreover, having both an awareness and a positive affective relationship with another group member amplified their positive effect on expertise seeking. Last, individuals who had more negative affective ties were less likely to leverage the positive impact of each awareness relationship on expertise seeking.     

Selective and faithful imitation at 12 and 15 months

Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.

Religiosity,coping, and suicidality within the religious Zionist community of Israela thematic qualitative analysis

The relationship between religion and mental health has been the subject of extensive research, particularly in recent years. The issues of coping and suicidality have also been widely studied. Significantly, however, how religious people cope with harsh life situations is an area which has been overlooked. The present study based on 18 semi-structured interviews, analyses have members of the Religious Zionist community in Israel cope with harsh life situations. Although the study confirms the conclusions of previous research – in general religion creates a buffer to suicide – the results showed a relatively low impact of religiosity on coping: in general these religious interviewees found it difficult to access their religiosity during harsh life situations. The paper suggests a range of explanations, for example the complexity of personal and collective identities which characterise this group, or – more significantly – the possibilty that religious coping is not actually absent but is only available in a second, later stage of coping.     

Obtaining guilty knowledge in human intelligence interrogations: Comparing accusatorial and information-gathering approaches with a novel experimental paradigm

Substantial research has assessed interrogations seeking to obtain a criminal confession, and consequently much has been learned regarding the potential problems with confession evidence. However, an increasing focus on counter-terrorism, and therefore intelligence interrogations, reveals an obvious gap in the literature. Intelligence interrogations are primarily focused on collecting information from individuals as opposed to a confession linked to an alleged event, and little of the extant psychological literature can speak directly to such a scenario. The current research developed an experimental paradigm to test interrogation approaches in an intelligence-gathering context, providing a method for gathering empirical data on human intelligence collection. In the first implementation of this paradigm, accusatorial and information-gathering interrogation strategies were tested using a procedure high in psychological realism. Results indicate that an information-gathering approach yields more relevant information than an accusatorial approach and leads to more diagnostic impressions by third party observers.     

Moderator effects of attitudinal ambivalence on attitude–behaviour relationships

Attitudinal ambivalence is generally construed as existing when the same attitude object is evaluated simultaneously as both positive and negative. The present research examined the moderating role of attitudinal ambivalence (as assessed by split‐semantic differential measure) on the relationship between bipolar semantic differential measures of attitude and subsequent behaviour using moderated regression analysis. In Study 1, higher levels of attitudinal ambivalence were shown to result in weaker attitude–behaviour relationships for eating a low‐fat diet (N = 140) and eating 5 portions of fruit and vegetables per day (N = 142). Study 2 (N = 361) replicated this effect when also including a measure of past behaviour for eating a low‐fat diet. Implications for understanding the relationship between attitudes and behaviour are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Audiographic communication for distance counselling: a feasibility study

To explore the feasibility of conducting counselling or therapy that involves image making via the Internet, and simultaneously to identify new issues to consider when implementing online counselling services, 10 people selected for their relevant expertise were invited to use an audiographic telecommunication system and to comment on it. Content analysis of focus group discussions and interviews yielded the following significant issues: (a) concerns about technical failure, (b) relevance for people with disabilities, (c) the need for clinical procedures and communication guidelines, and (d) lack of shared physical presence. The co-researchers considered this form of distance delivery to be viable, and identified parameters that would ensure safe and ethical delivery. Implications for practice and future development are discussed.     

Major depression,chronic minor depression,and the five‐factor model of personality

Fifty‐eight outpatients with major depression completed the NEO Personality Inventory at intake (time 1) and after up to three months of anti‐depressant treatment (time 2). Within this group, 26 patients met additional Research Diagnostic Criteria for chronic minor depression. Repeated‐measures analyses revealed significant decreases in Neuroticism scores, and significant increases in Extraversion and Conscientiousness scores, from time 1 to time 2 for both patient groups. In addition, despite similar symptom severity at time 2, the patients with major depression+chronic minor depression scored significantly higher on the Angry Hostility facet of Neuroticism and significantly lower on Agreeableness than those with major depression alone. We suggest from these findings that Angry Hostility and low Agreeableness may represent a trait vulnerability in individuals with chronic minor depression that persists even following remission of the major depressive state, and that this may help to explain their high rates of relapse and recurrence.

Losing Control: The effects of educational restructuring on waking and dream life

This paper focuses on the restructuring of the educational system in England over the last 14 years. It proposes that frequent changes to the system have resulted in negative emotions for many teachers which in turn have implications for the children's well-being. One of the negative feelings reported by teachers in subjective studies of their working experiences is a loss of control of the content and methodology of their work. This feeling re-emerges in school-related anxiety dreams, the content of which was studied in a sample of 10 teachers and four headteachers. The article raises issues for managers, suggesting that they need to ensure that the spiritual and emotional lives of the teachers are safeguarded in order to protect those of the children.
