The effect of feedback delay and feedback type on perceptual category learning: the limits of multiple systems

Evidence that learning rule-based (RB) and information-integration (II) category structures can be dissociated across different experimental variables has been used to support the view that such learning is supported by multiple learning systems. Across 4 experiments, we examined the effects of 2 variables, the delay between response and feedback and the informativeness of feedback, which had previously been shown to dissociate learning of the 2 types of category structure. Our aim was twofold: first, to determine whether these dissociations meet the more stringent inferential criteria of state-trace analysis and, second, to determine the conditions under which they can be observed. Experiment 1 confirmed that a mask-filled feedback delay dissociated the learning of RB and II category structures with minimally informative (yes/no) feedback and also met the state-trace criteria for the involvement of multiple latent variables. Experiment 2 showed that this effect is eliminated when a less similar, fixed pattern mask is presented in the interval between response and feedback. Experiment 3 showed that the selective effect of feedback delay on II learning is reduced with fully informative feedback (in which the correct category is specified after an incorrect response) and that feedback type did not dissociate RB and II learning. Experiment 4 extended the results of Experiment 2, showing that the differential effect of feedback delay is eliminated when a fixed pattern mask is used. These results pose important challenges to models of category learning, and we discuss their implications for multiple learning system models and their alternatives.     

A qualitative investigation into the online counselling relationship: To meet or not to meet,that is the question

Background and aim: Online counselling, as a psychotherapeutic approach, provokes debate amongst practitioners and researchers concerning its efficacy and validity. This reflexive study extends existing research into the nature of the online counselling relationship when it is conducted asynchronously (by email) and explores the possibility this approach may facilitate both online and face‐to‐face therapeutic engagement. Method: Semi‐structured interviews were conducted electronically with ten former email counselling clients of a university counselling service and six counsellors delivering email counselling in other higher education settings, to explore, in depth, their experiences of the online therapeutic relationship and its impact on the counselling process and outcomes. These were analysed using Interpretative Phenomenological Analysis (IPA). Findings: Four areas of focus emerged relating to: (1) the importance of the structure and processes involved; (2) their impact on thinking and feeling; (3) their impact on self and relationships (within and outside counselling), and (4) changes that followed email counselling. Having ‘time to think’ within the asynchronous exchanges, the anonymity and disinhibition afforded by the online medium, the creation of transitional space and the rich use of metaphor, visualisation and imagery all contributed to a sense of empowerment and relational depth for individuals who might have otherwise avoided seeking help. This led to positive change in many cases and for some, facilitated subsequent face‐to‐face counselling. Implications: The findings support the provision of counselling and therapy online and particularly its integration within existing face‐to‐face services.     

Domain-specific perfectionism in intercollegiate athletes: Relationships with perceived competence and perceived importance in sport and school

ObjectivesTo examine the domain-specific nature of perfectionism in sport and school, and to examine potential links between domain-specific perceived competence, perceived importance (task value), and perfectionism in sport and school.Design and MethodA total of 255 male and female varsity student-athletes from a successful intercollegiate sport program completed domain-specific (i.e., sport and school) versions of Hewitt and Flett's (1991) Multidimensional Perfectionism Scale (HF-MPS). Participants also completed an inventory designed to assess perceived competence (PC) in sport versus school and perceived importance (PI) of success in sport versus school.ResultsExploratory factor analyses conducted on perfectionism data indicated that perfectionist orientations were organized around domain-specific as opposed to global perfectionist tendencies. Regression analyses indicated that PC was a significant predictor of domain-specific levels of self-oriented and socially prescribed perfectionism (ps < .05), and PI was a significant predictor of domain-specific levels of self-oriented, socially prescribed, and other-oriented perfectionism (ps < .001). A repeated-measures MANOVA revealed that student-athletes had significantly higher levels of perfectionism in sport than school (ps < .0001) across all three HF-MPS subscales.ConclusionResults reinforce the value of measuring perfectionism as a domain-specific (rather than global) personality disposition, and identify the potential role that perceived competence and perceived importance may play in the development of domain-specific perfectionism.     

Correlates of satisfaction with body function and body appearance in middle- and older aged adults: The activity counseling trial (ACT)

Abstract

This study examined the dimensional structure and correlates of body satisfaction among middle-aged and older adult men (n = 471) and women (n = 383) who were participants in the Activity Counseling Trial. Correlates were grouped as (1) fitness parameters, (2) demographic characteristics, and (3) components of subjective well-being. Factor analyses demonstrated that body function and body appearance were independent components of satisfaction in this population. Body composition and cardiorespiratory fitness were directly related to satisfaction with body appearance; however, satisfaction with body function was most strongly related in expected directions to measures of subjective well-being. Age was positively related to both measures of body satisfaction, whereas data on race revealed that blacks were more satisfied with their body appearance and function than whites. The observed relationships for body satisfaction suggest that older adults may value body function more than body appearance. Furthermore, the associations of race and age with body satisfaction have important implications for intervention research.     

Parent Education in Youth Sport: A Community Case Study of Parents,Coaches, and Administrators

The present community case study was designed to highlight parent, coach, and administrator perceptions of community-based parent education in a youth sport community in the Rocky Mountain region of the United States. Interviews with parents (n?=?12), coaches (n?=?13), and administrators (n?=?11) were interpreted inductively using constructivist thematic analysis. Nine emergent categories are highlighted, including parents’ sport goals for their children, parents’ involvement in youth sport including impacts of involvement on children, and barriers to implementing parent education, as well as potential content for parent education. A proposed sequential framework informing community-based parent education, as well as suggestions for further action, and study limitations are included.     

Is there an optimal factor structure of the Positive and Negative Syndrome Scale in patients with first‐episode psychosis?

The Positive and Negative Syndrome Scale (PANSS) is the most widely used scale to assess a variety of symptoms in patients with schizophrenia and other psychoses. The factor structure of the PANSS has been examined with confirmatory factor analyses in several studies, but not in a well‐defined first‐episode psychosis sample. The aim of this paper is to examine the statistical fit of five different PANSS models in a first‐episode, non‐affective psychosis sample. Confirmatory factor analyses were performed on PANSS data (n = 588). A main criterion for best fit was defined as the Expected Cross Validation Index (ECVI). No tested model revealed an optimally satisfactory model fit index. The Wallwork/Fortgang five‐factor model demonstrated the most optimal psychometric properties. The corresponding subscales of all evaluated five‐factor models were strongly intercorrelated. The Wallwork/Fortgang five‐factor model was found to be statistically and clinically ideal among patients with first‐episode psychosis. Therefore, we recommend this model in forthcoming studies among patients with first‐episode psychosis. However, to prevent the loss of clinically valuable information on an item level, we do not recommend removing any items from the original form. Our study also implies that the specific choice of model will not have a substantial effect on outcome results in studies on the course and outcome in first‐episode psychosis.     

Fluency Profiling System: An automated system for analyzing the temporal properties of speech

The temporal characteristics of speech can be captured by examining the distributions of the durations of measurable speech components, namely speech segment durations and pause durations. However, several barriers prevent the easy analysis of pause durations: The first problem is that natural speech is noisy, and although recording contrived speech minimizes this problem, it also discards diagnostic information about cognitive processes inherent in the longer pauses associated with natural speech. The second issue concerns setting the distribution threshold, and consists of the problem of appropriately classifying pause segments as either short pauses reflecting articulation or long pauses reflecting cognitive processing, while minimizing the overall classification error rate. This article describes a fully automated system for determining the locations of speech–pause transitions and estimating the temporal parameters of both speech and pause distributions in natural speech. We use the properties of Gaussian mixture models at several stages of the analysis, in order to identify theoretical components of the data distributions, to classify speech components, to compute durations, and to calculate the relevant statistics.     

Can Giving Clients a Choice in Food Selection Help to Meet Their Nutritional Needs?: Investigating a Novel Food Bank Approach for Asylum Seekers

The aim of this research was to investigate whether a foodbank working directly with people seeking asylum and incorporating client choice, located in Melbourne Australia, can meet the nutritional requirements of asylum seekers. A structured process of direct observation was used to document each item selected from the foodbank in a single basket. The food baskets of 116 asylum seekers, all over the age of 18, who were wholly reliant on the foodbank were analysed for nutritional content. Analysis revealed that an average basket was deficient in almost all micronutrients including vitamins A, C, D and E, folate, calcium and zinc. Baskets were found to have higher than recommended levels of sodium and fat. Despite the foodbank allowing clients to individually select the food they wish to consume, the food baskets remained nutritionally inadequate. This may be due the structure of the foodbank, the nature of relying on community donations of food and complexities surrounding healthy food choice among asylum seekers. Providing choice around food acquisition is one way to promote dignity in the refugee determination process; however, this may not be the best way to provide a nutritionally adequate diet. In addition to donor guidelines that highlight the need for nutritionally and culturally appropriate foods, further supplementary nutritional education may be required to encourage healthy food choices where they exist.     

Blind spots in the search for happiness: Implicit attitudes and nonverbal leakage predict affective forecasting errors

We investigated implicit knowledge and affective forecasting, reasoning that although conscious evaluations are available to people when predicting their future emotional responses, nonconscious evaluations are not. However, these automatically-activated evaluations should contribute to in-the-moment emotional experiences, and thus they should account for misforecasts (i.e., discrepancies between affective forecasts and actual experiences). We conducted two studies to explore affective misforecasts, using food items as stimuli. In Study 1, participants' implicit attitudes (but not their explicit attitudes) predicted misforecasts of food enjoyment, supporting the role of nonconscious evaluations in affective forecasting errors. In Study 2, we examined participants' facial expressions (another index of nonconscious evaluation) upon the presentation of food items, and we found that these nonverbal behaviors predicted affective misforecasts as well. In sum, although nonconscious evaluations are unavailable when anticipating the future, they may contribute to one's in-the-moment experiences and thus serve as blind spots in affective forecasting.
