Time estimation: does the reference memory mediate the effect of knowledge of results?

This study presents evidence for the role of knowledge of results (KR) in the estimation of medium time intervals (4-12 s durations). Experiment 1 tested the hypothesis that KR operates at the same stage of temporal processing as attention. The absence of an interaction of attention and KR is taken as evidence against this hypothesis. Experiments 2 and 3 further studied the effects of KR in a reproduction and a production task, respectively. The effects of KR were small in the reproduction and substantial in the production task. The results are interpreted in terms of a clock-based timing model and the findings taken together converge on the interpretation that KR affects the reference memory (RM), rather than the other components of the model.     

Hippocampal damage and exploratory preferences in rats: memory for objects, places, and contexts

Rats have a natural tendency to spend more time exploring novel objects than familiar objects, and this preference can be used as an index of object recognition. Rats also show an exploratory preference for objects in locations where they have not previously encountered objects (an index of place memory) and for familiar objects in contexts different from those in which the objects were originally encountered (an index of context memory). In this experiment, rats with cytotoxic lesions of the hippocampal formation were tested on all three versions of the novelty-preference paradigm, with a 5-min retention interval between the familiarization and test phases. Rats with sham lesions displayed a novelty preference on all three trial types, whereas the rats with hippocampal lesions displayed a novelty preference on Object trials but did not discriminate between the objects on Place trials or Context trials. The findings indicate that hippocampal damage impairs memory for contextual or spatial aspects of an experience, whereas memory for objects that were part of the same experience are left relatively intact.     

Examining Factors Associated with Primary Care and Continuity of Care Among Adults with Severe Mental Illness

A number of studies have consistently reported that there is a greater prevalence of mental illness among the most socioeconomically disadvantaged. At the same time, there is evidence that services are not optimally accessed by the most socioeconomically disadvantaged; the most in need of care are also the most likely to have unmet healthcare needs. Of people with mental illnesses, those with severe mental illnesses (SMI) are the most at risk of poverty and the least likely to have optimal care. In the past, specialized community mental health services have been identified as the primary provider for people with SMI. However, there is growing interest in using the primary care setting as the main source of mental health care where both medical treatment and psychotherapy can be accessed. In this paper, we examine factors related to primary care use (and in turn, pharmacologic and psychotherapies) for people who are socioeconomically disadvantaged and who have a SMI.     

Therapeutic immediacy across long-term psychodynamic psychotherapy: an evidence-based case study

C. E. Hill (2004) recently developed the concept of therapist immediacy to capture discussion by the therapist about the therapeutic relationship that occurs in the here-and-now of a therapy session. This concept has been expanded to include discussion about the therapeutic relationship by both the client and therapist, captured by the term therapeutic immediacy (K. Kuutmann & M. Hilsenroth, 2011). Although prior research has examined the use of therapeutic immediacy across short-term treatment, the present study is the first to examine the use of immediacy across a long-term (4 years) psychotherapy. Also, this is the first study to assess the interrater reliability of therapeutic immediacy, which was found to achieve good to excellent levels across raters. The most frequently used categories of client and therapist immediacy are presented. Finally, the authors provide an in-depth qualitative examination of 5 therapeutic immediacy segments across the treatment judged by the raters to have high levels of depth/intensity (4.5 or higher out of 5) to examine the role of therapeutic immediacy in exploring meaningful treatment issues. Clinical utility, potential limitations, and future research on therapeutic immediacy are discussed.     

Rehearsal dynamics in elementary school children

Several studies on free recall suggest that processes responsible for recall are analogous to processes responsible for rehearsal. In children, the relationship between cumulative rehearsal and recall performance has been proven to be critical; however, the locus of the effect of rehearsal is not yet fully understood. To unfold the mechanisms that come into play in an overt rehearsal free recall task, we assessed rehearsal and recall sequences in children between 8 and 10 years of age. These sequences give information about the context in which items are repeated and rearranged throughout the list and subsequently recalled. Rehearsal sequences consisted mainly of items from neighboring list positions in their original temporal order. The same characteristics were true for recall sequences. Qualitatively, order effects during study and recall did not differ over age groups. However, in older children who were using cumulative rehearsal more intensively, successive rehearsal and recall of items in their original order was more pronounced. Therefore, we suggest that a main feature of item rehearsal with regard to facilitating recall is the strengthening of interitem associations based on the temporal order within a list and that this characteristic develops with age.     

Choosing housemates and justifying age,gender, and ethnic discrimination

This study examines the explanations and justifications offered by those engaged in selecting housemates. The rationale for the research follows the recent housing demographic, whereby shared living has become increasingly popular among young adults in Western countries. This study sought to address the surprising lacuna in the extant research through the application of discursive psychology to understanding prejudice and discrimination within the context of contemporary social and political sanctions against openly discussing prejudice. Data were drawn from interviews with young New Zealanders aged from early twenties to early thirties who were experienced with house sharing. Detailed results are presented involving discrimination based on age, gender, and ethnicity. The study found that rigid narrow preferences were stated with respect to age, gender was less important, and ethnicity was talked about cautiously, especially if there was the possibility of significant cultural differences or language barriers.     

Can Rachman's indirect pathways be used to un-learn fear? A prospective paradigm to test whether children's fears can be reduced using positive information and modelling a non-anxious response

This study investigated whether children's fears could be un-learned using Rachman's indirect pathways for learning fear. We hypothesised that positive information and modelling a non-anxious response are effective methods of un-learning fears acquired through verbal information. One hundred and seven children aged 6-8 years received negative information about one animal and no information about another. Fear beliefs and behavioural avoidance were measured. Children were randomised to receive positive verbal information, modelling, or a control task. Fear beliefs and behavioural avoidance were measured again. Positive information and modelling led to lower fear beliefs and behavioural avoidance than the control condition. Positive information was more effective than modelling in reducing fear beliefs and both methods significantly reduced behavioural avoidance. The results support Rachman's indirect pathways as viable fear un-learning pathways and supports associative learning theories.     

Adult Psychological Distress and Self-Worth Following Child Verbal Abuse

Despite the proliferation of child maltreatment research over the last 30 years, there remains a dearth of research examining the long-term effects of child psychological maltreatment (CPM), particularly child verbal abuse (CVA). Using a college sample of 173 participants from a Southeastern university, this study examined the role of gender and perpetrator relationship in predicting psychological distress and self-worth of adults exposed to CVA. Maternal CVA emerged as a significant predictor of lower levels of self-worth in adult daughters and sons as well as greater psychological distress in adult daughters. Paternal CVA did not emerge as a significant predictor of greater psychological distress or lower levels of self-worth in either adult daughters or sons.     

Mental rotation performance in soccer players and gymnasts in an object-based mental rotation task

In this study, the effect of motor expertise on an object-based mental rotation task was investigated. 60 males and 60 females (40 soccer players, 40 gymnasts, and 40 non-athletes, equivalent males and females in each group) solved a psychometric mental rotation task with both cube and human figures. The results revealed that all participants had a higher mental rotation accuracy for human figures compared to cubed figures, that the gender difference was reduced with human figures, and that gymnasts demonstrated a better mental rotation performance than non-athletes. The results are discussed against the background of the existing literature on motor experts, mental rotation performance as well as the importance of the testing situation and the test construction.     

Mothers,Fathers, Gender Role,and Time Parents Spend with Their Children

To examine the relationships among the sex of the parent, gender role, and the time parents spend with their children, 272 parents completed the Bem Sex-Role Inventory, a questionnaire about the time spent with their children, and a demographics questionnaire. Analyses indicated that neither the sex of the parent nor gender role was predictive of the amount of time parents were spending in direct interaction with or being accessible to their children. The sex of the parent, qualified by earning status, was predictive of the level of responsibility parents had for child-related activities. Further, the sex of the parent, qualified by femininity, was predictive of parental satisfaction with level of child-related responsibilities. These results emphasize the importance of examining parental characteristics in relation to the time parents spend with their children and their levels of responsibility for child-related activities.
