Semantic priming,not repetition priming,is to blame for false hearing

Contextual and sensory information are combined in speech perception. Conflict between the two can lead to false hearing, defined as a high-confidence misidentification of a spoken word. Rogers, Jacoby, and Sommers (Psychology and Aging, 27(1), 33–45, 2012) found that older adults are more susceptible to false hearing than are young adults, using a combination of semantic priming and repetition priming to create context. In this study, the type of context (repetition vs. sematic priming) responsible for false hearing was examined. Older and young adult participants read and listened to a list of paired associates (e.g., ROW–BOAT) and were told to remember the pairs for a later memory test. Following the memory test, participants identified words masked in noise that were preceded by a cue word in the clear. Targets were semantically associated to the cue (e.g., ROW–BOAT), unrelated to the cue (e.g., JAW–PASS), or phonologically related to a semantic associate of the cue (e.g., ROW–GOAT). How often each cue word and its paired associate were presented prior to the memory test was manipulated (0, 3, or 5 times) to test effects of repetition priming. Results showed repetitions had no effect on rates of context-based listening or false hearing. However, repetition did significantly increase sensory information as a basis for metacognitive judgments in young and older adults. This pattern suggests that semantic priming dominates as the basis for false hearing and highlights context and sensory information operating as qualitatively different bases for listening and metacognition.     

Frequency of Interpersonal Trauma Types,Avoidant Attachment,Self-Compassion,and Interpersonal Competence: A Model of Persisting Posttraumatic Symptoms

Given limited knowledge about how psychosocial factors interact to modulate posttraumatic stress symptoms, this study evaluated an integrative model proposing that experiencing more interpersonal trauma types (e.g., abuse, assault, rape, etc.) leads to greater avoidant attachment and lower self-compassion, which limits the development and use of effective interpersonal skills. In turn, lower levels of self-compassion and interpersonal competence perpetuate posttraumatic symptoms. Anonymous trauma-experienced adults (n = 132) completed self-report measures in an online study hyperlinked on trauma support websites. Data were subjected to confirmatory factor analysis and structural equation modeling, which provided support for the hypothesized model. Specifically, higher frequency of interpersonal trauma types experienced was linked to higher avoidant attachment and lower self-compassion, which in turn were associated with lower interpersonal competence, which correlated with greater posttraumatic stress symptoms. Although cross-sectional data cannot address directionality of associations, this study’s findings emphasize the potential utility of future longitudinal research designed to examine possible causal relationships among these specific psychosocial factors. For example, study findings suggest that those who experience more types of interpersonal trauma and who are characterized by avoidant attachment and lower self-compassion and interpersonal competence may be the most susceptible to experiencing severe posttraumatic symptoms. However, findings also suggest that efforts to increase self-compassion and interpersonal skills may help reduce symptoms.     

Neurofeedback Treatment of Depression and Anxiety

A robust body of research documents that there are biological predispositions that often exist for depression, anxiety, and obsessive–compulsive disorder. However, new research has shown that medication is only mildly more effective than placebo in the treatment of these problems. In treating these conditions, neurofeedback (EEG biofeedback) may offer an alternative to invasive treatments such as medication, ECT, and intense levels of transcrancial magnetic stimulation. This paper reviews the neurofeedback literature with these problems, finding particularly positive research support for the treatment of anxiety disorders. New findings on the neurofeedback treatment of depression are presented.     

A bifactor model of negative affectivity: fear and distress components among younger and older youth

The Positive and Negative Affect Schedule for Children (PANAS-C) is a 27-item youth-report measure of positive affectivity and negative affectivity. Using 2 large school-age youth samples (clinic-referred sample: N = 662; school-based sample: N = 911), in the present study, we thoroughly examined the structure of the PANAS-C NA and PA scales and fit a bifactor model to the PANAS-C NA items. Our exploratory factor analytic results demonstrated that negative affectivity is comprised of 2 main components-NA: Fear and NA: Distress-specifically among older youth. A bifactor model also evidenced the best model fit relative to a unidimensional and second-order factor structure of the PANAS-C NA items. The NA: Fear group factor evidenced significant correspondence with external criterion measures of anxiety. However, the original PANAS-C NA scale evidenced equal (and in some cases greater) correspondence with criterion measures of anxiety. We thus recommend continued usage and interpretation of the full PANAS-C NA scale despite the identification of the fear and distress group factors underlying general negative affectivity. The identification of these fear and distress group factors nonetheless suggest that negative affectivity may be comprised largely of a fear and distress component among older youth. The implications of these findings are discussed in relation to better understanding the structure of psychopathology across childhood development and informing the development of future treatments of negative emotions.     

Decay functions and criminal spatial processes: geographical offender profiling of volume crime

Although it is now well established across diverse samples that the frequency of offending ‘decays’ as distance from the home/base increases, it remains unclear what form of decay function best characterises this relationship. Different forms of decay function reflect different patterns and rates of decrease in the likelihood of offending as distance from the home/base increases. These different patterns imply rather different underlying psychological processes. Therefore, considerations of the particular function characterising distance decay elucidate explanations of offender spatial behaviour. To bring to light the possible psychological and behavioural processes inherent in offending distance decay, the present study examined the fit of logarithmic, negative exponential, and quadratic decay functions to the distribution of the distances travelled to offend by a sample of 70 prolific burglars from the UK. It is argued that these functions are consistent with the operation of perceptual processes of magnitude estimation, friction or effort effects, and the influences of cost‐benefit assessments, respectively. The results indicate that offending distance decay patterns most closely fit the logarithmic function, consistent with Stevens' perceptual processes of distortion in magnitude estimation, whilst not ruling out additional processes relating to the increased effort required in travelling greater distances to offend. Because most geographical profiling systems are built upon the distance decay function, the impact of utilising the different forms of function on the accuracy of geographic profiles was also assessed utilising ‘search cost’ calculations. The results showed little impact of applying different decay functions. Thus, whilst the decay function does have important theoretical implications for understanding offender spatial behaviour, it is noted that the particular variant used does not significantly impact on the effectiveness of geographical profiling systems as they currently exist.

Rapid fast-mapping abilities in 2-year-olds

Learning a new word consists of two primary tasks that have often been conflated into a single process: referent selection, in which a child must determine the correct referent of a novel label, and referent retention, which is the ability to store this newly formed label-object mapping in memory for later use. In addition, children must be capable of performing these tasks rapidly and repeatedly as they are frequently exposed to novel words during the course of natural conversation. Here we used a preferential pointing task to investigate 2-year-olds’ (N = 72) ability to infer the referent of a novel noun from a single ambiguous exposure and their ability to retain this mapping over time. Children were asked to identify the referent of a novel label on six critical trials distributed throughout the course of a 10-min study involving many familiar and novel objects. On these critical trials, images of a known object and a novel object (e.g., a ball and a nameless artifact constructed in the laboratory) appeared on two computer screens and a voice asked children to “point at the _____ [e.g., glark].” Following label onset, children were allowed only 3 s during which to infer the correct referent, point at it, and potentially store this new word-object mapping. In a final posttest trial, all previously labeled novel objects appeared and children were asked to point to one of them (e.g., “Can you find the glark?”). To succeed, children needed to have initially mapped the novel labels correctly and retained these mappings over the course of the study. Despite the difficult demands of the current task, children successfully identified the target object on the retention trial. We conclude that 2-year-olds are able to fast map novel nouns during a brief single exposure under ambiguous labeling conditions.     

The influence of individual attachment styles on group members' experience of therapist transitions

Attachment theory has recently been applied to clinical practice in an effort to improve understanding and treatment of the maladaptive relational patterns clients bring to therapy. While most of this research has focused on individual therapy, interest in the application of attachment theory to group psychotherapy is growing. This paper will explore the impact of clients' attachment styles on their experiences of co-therapist transition in an ongoing psychodynamic therapy group. This discussion will elucidate how knowledge of attachment theory and an understanding of clients' individual attachment styles can be useful in predicting responses to therapist-initiated terminations and transitions.     

Are you interested? A meta-analysis of relations between vocational interests and employee performance and turnover

A common belief among researchers is that vocational interests have limited value for personnel selection. However, no comprehensive quantitative summaries of interests validity research have been conducted to substantiate claims for or against the use of interests. To help address this gap, we conducted a meta-analysis of relations between interests and employee performance and turnover using data from 74 studies and 141 independent samples. Overall validity estimates (corrected for measurement error in the criterion but not for range restriction) for single interest scales were .14 for job performance, .26 for training performance, -.19 for turnover intentions, and -.15 for actual turnover. Several factors appeared to moderate interest-criterion relations. For example, validity estimates were larger when interests were theoretically relevant to the work performed in the target job. The type of interest scale also moderated validity, such that corrected validities were larger for scales designed to assess interests relevant to a particular job or vocation (e.g., .23 for job performance) than for scales designed to assess a single, job-relevant realistic, investigative, artistic, social, enterprising, or conventional (i.e., RIASEC) interest (.10) or a basic interest (.11). Finally, validity estimates were largest when studies used multiple interests for prediction, either by using a single job or vocation focused scale (which tend to tap multiple interests) or by using a regression-weighted composite of several RIASEC or basic interest scales. Overall, the results suggest that vocational interests may hold more promise for predicting employee performance and turnover than researchers may have thought.     

Effects of daily morphine administration and deprivation on choice and demand for remifentanil and cocaine in rhesus monkeys

Choice procedures have indicated that the relative reinforcing effectiveness of opioid drugs increases during opioid withdrawal. The demand curve, an absolute measure of reinforcer value, has not been applied to this question. The present study assessed whether mild morphine withdrawal would increase demand for or choice of remifentanil or cocaine. Four rhesus monkeys chose between remifentanil and cocaine during daily sessions. Demand curves for both drugs were subsequently obtained. The effects of daily injections of 3.2 mg/kg morphine on both choice and demand for these drugs was assayed 3 and 20.5 hr after each morphine injection, and then during a postmorphine period. Three hours following morphine injections, choice of remifentanil over cocaine decreased and demand for remifentanil--but not cocaine--became more elastic. During morphine withdrawal (20.5 hr postinjection), choice of remifentanil increased and remifentanil demand became more inelastic in 3 of 4 monkeys. Cocaine demand also became more inelastic during this period. Four to five weeks following the morphine regimen, demand for both drugs was more inelastic relative to the initial determination. The results suggest that both the relative and absolute reinforcing effectiveness of remifentanil decreased following morphine administration and increased during morphine withdrawal. The absolute reinforcing effectiveness of cocaine also increased during morphine withdrawal. In addition, extended exposure to drug self-administration and/or exposure to the morphine regimen produced long-term increases in demand for both drugs.     

A Psychometric Analysis of the Revised Child Anxiety and Depression Scales—Parent Version in a School Sample

The Revised Child Anxiety and Depression Scale—Parent Version (RCADS-P) is a parent-report questionnaire of youth anxiety and depression with scales corresponding to the DSM diagnoses of separation anxiety disorder, social phobia, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, and major depressive disorder. The RCADS-P was recently developed and has previously demonstrated strong psychometric properties in a clinic-referred sample (Ebesutani et al., Journal of Abnormal Child Psychology 38, 249–260, 2010b). The present study examined the psychometric properties of the RCADS-P in a school-based population. As completed by parents of 967 children and adolescents, the RCADS-P demonstrated high internal consistency, test-retest reliability, and good convergent/divergent validity, supporting the RCADS-P as a measure of internalizing problems specific to depression and five anxiety disorders in school samples. Normative data are also reported to allow for the derivation of T-scores to enhance clinicians’ ability to make classification decisions using RCADS-P subscale scores.
