Language, perception, and the schematic representation of spatial relations

Schemas are abstract nonverbal representations that parsimoniously depict spatial relations. Despite their ubiquitous use in maps and diagrams, little is known about their neural instantiation. We sought to determine the extent to which schematic representations are neurally distinguished from language on the one hand, and from rich perceptual representations on the other. In patients with either left hemisphere damage or right hemisphere damage, a battery of matching tasks depicting categorical spatial relations was used to probe for the comprehension of basic spatial concepts across distinct representational formats (words, pictures, and schemas). Left hemisphere patients underperformed right hemisphere patients across all tasks. However, focused residual analyses using voxel-based lesion-symptom mapping (VLSM) suggest that (1) left hemisphere deficits in the representation of categorical spatial relations are difficult to distinguish from deficits in naming these relations and (2) the right hemisphere plays a special role in extracting schematic representations from richly textured pictures.     

The Role of Socio-Psychological Determinants in the Sexual Behaviors of Latina Early Adolescents

Although a large body of research has examined the negative outcomes that occur when Latina adolescents engage in sexual activity, relatively little research explores the determinants that may contribute to these behaviors. In the current study, an ecological community psychological approach was used to examine the impact that substance use, sexual self-efficacy, parental communication, normative peer pressure, acculturation, educational aspirations, grades, and gang activity have on adolescent sexual behavior. The sample consisted of 217 participants (mean age of 14.6) who self-identified as Latina from the greater Los Angeles metropolitan area of California in the United States. The results indicate that about a third of the sample had engaged in one or more sexual behaviors. Overall, greater usage of substances was associated with greater numbers of sexual behaviors. Girls who reported engaging in two or more sexual behaviors reported more frequent marijuana and alcohol use. The girls who reported high sexual self-efficacy engaged in few to no sexual behaviors. Additionally, parental communication, normative peer pressure, acculturation, and educational aspirations were unrelated to their sexual behavior. However, the majority of girls who reported receiving good grades also reported no sexual activity. Moreover, girls who reported no sexual behavior also reported no gang activity. The results indicate that a multi-level approach to examining the psycho-social determinants of sexual activity in Latina girls provides a more comprehensive picture of their sexual decision making.     

Hierarchical modeling of contingency-based source monitoring: A test of the probability-matching account

According to the probability-matching account of source guessing (Spaniol & Bayen, Journal of Experimental Psychology: Learning, Memory, and Cognition 28:631–651, 2002), when people do not remember the source of an item in a source-monitoring task, they match the source-guessing probabilities to the perceived contingencies between sources and item types. In a source-monitoring experiment, half of the items presented by each of two sources were consistent with schematic expectations about this source, whereas the other half of the items were consistent with schematic expectations about the other source. Participants’ source schemas were activated either at the time of encoding or just before the source-monitoring test. After test, the participants judged the contingency of the item type and source. Individual parameter estimates of source guessing were obtained via beta-multinomial processing tree modeling (beta-MPT; Smith & Batchelder, Journal of Mathematical Psychology 54:167–183, 2010). We found a significant correlation between the perceived contingency and source guessing, as well as a correlation between the deviation of the guessing bias from the true contingency and source memory when participants did not receive the schema information until retrieval. These findings support the probability-matching account.     

The rehabilitation of primary object relations in the first year of intensive therapy with a severely deprived child

The following is an account of the first year of a therapy carried out in the public sector of a child born at the beginning of 1990 in an eastern European country and brought up in a home for abandoned children until he was placed with Italian parents at the end of 1995. I shall describe the child's initial psychological state, vigorous, but desperate, and then go on to describe the course of the first year of therapy, focusing in particular on the sessions of the from period, in which, apart from the quality and intensity of his anxiety, his need to fie this anxiety by retracing the stages of his first object experiences is clear.     

Acceptance in Cognitive Behavioral Psychotherapies: Different or the Same?

Acceptance is a key construct in both rational emotive behavior therapy (REBT) and acceptance and commitment therapy (ACT). The objectives of this study were to assess and compare the properties of ACT acceptance with those of REBT acceptance in predicting emotions. A sample of 112 subjects, comprising different educational and occupational status, completed three measures of acceptance (REBT and ACT), two of mindfulness, as well as completing depression and anxiety scales. Both ACT acceptance as process and REBT acceptance could predict significant ACT acceptance as outcome. Mindfulness as a trait also predicted the level of ACT outcome acceptance as well as the level of REBT acceptance, but mindfulness as process predicted only ACT outcome acceptance. The results show that REBT acceptance, ACT acceptance and mindfulness can explain anxiety and depression in different ways. The results show that the difference between ACT acceptance and REBT acceptance primary concern the process of acceptance, most likely due to the underlying cognitive processing. The outcome acceptance and emotional level are similar in the two conditions. Future research should employ multiple cognitive measurements.     

Perception of emotional expression in musical performance

Expression in musical performance is largely communicated by the manner in which a piece is played; interpretive aspects that supplement the written score. In piano performance, timing and amplitude are the principal parameters the performer can vary. We examined the way in which such variation serves to communicate emotion by manipulating timing and amplitude in performances of classical piano pieces. Over three experiments, listeners rated the emotional expressivity of performances and their manipulated versions. In Experiments 1 and 2, timing and amplitude information were covaried; judgments were monotonically decreasing with performance variability, demonstrating that the rank ordering of acoustical manipulations was captured by participants' responses. Further, participants' judgments formed an S-shaped (sigmoidal) function in which greater sensitivity was seen for musical manipulations in the middle of the range than at the extremes. In Experiment 3, timing and amplitude were manipulated independently; timing variation was found to provide more expressive information than did amplitude. Across all three experiments, listeners demonstrated sensitivity to the expressive cues we manipulated, with sensitivity increasing as a function of musical experience.     

Expert testimony in child sexual abuse cases: The effects of evidence,coherence and credentials on juror decision making

Psychological experts have been used increasingly to testify in child sexual abuse cases, yet little research has investigated what specific factors make experts effective. This study examined the potential effects that credentials, evidence strength and coherence may have on juror decision making. Sixty‐four mock jurors read cases of child sexual abuse, followed by experts' testimony and rated guilt of the defendant, effectiveness of the expert testimony and credibility of the victim. Evidence strength and coherence of the testimony affected all dependent variables, and the interaction was significant. Guilt ratings of the defendant were lower and the victim was rated as less credible when both evidence strength and coherence were low. The credentials of the expert, however, had negligible impact. These findings indicate that experts can be effective and impact jurors when testimony is either high in coherence or high in evidence. Copyright © 2009 John Wiley & Sons, Ltd.     

Increasing access to low‐intensity interventions for childhood anxiety: A pilot study of a guided self‐help program for Scandinavian parents

Cognitive Behavior Therapy (CBT) is an effective treatment for child anxiety. However, access to treatment is limited. It has been suggested that low‐intensity formats of parent‐delivered CBT may improve access to treatment. Our aim was to develop and pilot‐test the acceptability and effect of a low‐intensity therapist‐guided parent‐delivered group program for anxious children (age 7–12 years) adjusted to the Scandinavian culture. The program required 1.5 hours of therapist‐time per family. Mothers, fathers and children reported on revised child anxiety and depression scale (RCADS) at referral, pre‐ and post‐treatment. Mothers and fathers also gave a qualitative account of their experiences. Thirty‐one families were enrolled and only one family dropped out. Mean age of the children was 9 years. Intent‐to‐treat analyses revealed significant reductions in anxiety and depressive symptoms from pre‐ to post‐treatment for all informants. Large effect sizes were found for child anxiety symptoms as reported by mothers and fathers, and for child depressive symptoms as reported by mothers. Medium to large effect sizes was found for the self‐reported anxiety symptoms by the children, and for depressive symptoms reported by both children and fathers. More than 93% of the parents would recommend the program. Results suggest that our program may provide a new approach to improve access to treatment for anxious children in Scandinavia; however, further research must be conducted before firm conclusions can be drawn.     

Integrative and Distributive Negotiation in Small Groups: Effects of Task Structure, Decision Rule, and Social Motive

This study examined the interactive effects of task structure, decision rule, and social motive on small-group negotiation processes and outcomes. Three-person groups negotiated either within an asymmetrical task structure (in which a majority of group members have compatible interests) or within a symmetrical task structure (in which no such majority exists). Groups negotiated either under unanimity rule or under majority rule, and group members were either egoistically or prosocially motivated. Results revealed cumulative main effects and the predicted three-way interaction: Groups in an asymmetrical task structure engaged in more distributive and less integrative behavior, reached lower joint outcomes, and experienced a less positive group climate especially when they had an egoistic rather than prosocial motivation and unanimity rather than majority rule applied. Theoretical implications and avenues for future research are discussed.
