Effects of training with added difficulties on RADAR detection

Three experiments simulating military RADAR detection addressed a training difficulty hypothesis (training with difficulty promotes superior later testing performance) and a procedural reinstatement hypothesis (test performance improves when training conditions match test conditions). Training and testing were separated by 1 week. Participants detected targets (either alphanumeric characters or vehicle pictures) occurring among distractors. Two secondary tasks were used to increase difficulty (a concurrent, irrelevant tone‐counting task and a sequential, relevant action‐firing response). In Experiment 1 , involving alphanumeric targets with rapid displays, tone counting during training degraded test performance. In Experiment 2, involving vehicle targets with both sources of difficulty and slower presentation times, training under relevant difficulty aided test accuracy. In Experiment 3, involving vehicle targets and action firing with slow presentation times, test accuracy tended to be worst when neither training nor testing involved difficult conditions. These results show boundary conditions for the training difficulty and procedural reinstatement hypotheses. Copyright © 2010 John Wiley & Sons, Ltd.     

Age group differences in self-reported aggressive driving perpetration and victimization

Aim

This study examined whether the predictors of self-reported aggressive driving perpetration and victimization vary across age groups.

Method

Based on data from a general-population telephone survey conducted from July 2002 through June 2005, three groups of drivers were examined: 18–34 year-olds (N = 1522), 35–54 year-olds (N = 2726), and 55 years of age or older (N = 1883). For each age group sample, logistic regression analyses examined self-reported aggressive driving perpetration and victimization in the last 12 months by measures of driving exposure, heavy drinking, cannabis use, and drinking-driving, while controlling for demographic factors.

Results

The prevalence of aggressive driving perpetration within the past year was highest for the youngest age group (51%), followed by the middle-aged group (37%), and then the oldest age group (18%). The same pattern of results was found for prevalence of aggressive driving victimization (54%, 47%, and 31%, respectively). Controlling for demographic factors, the predictors of perpetration were generally consistent across the age groups. The logistic regression model for the youngest drivers revealed that those who reported stressful driving, heavy drinking, and cannabis use had significantly increased odds of reporting perpetration of aggressive driving. For middle-aged and older drivers, stressful driving, driving on busy roads, cannabis use, and driving after drinking were associated with perpetration. In addition, increased mileage contributed to perpetration in the oldest group. The findings for victimization by aggressive driving were similar. The logistic regression model for the youngest age group identified stressful driving, cannabis use, and higher annual mileage as being associated with victimization. For the oldest age group, these same variables were significant predictors of victimization, in addition to driving on busy roads. The logistic regression for the middle-aged group identified the same predictors as that of the oldest age group; however, interestingly driving after drinking was found to predict lower victimization among middle-aged drivers.

Conclusions

Although the prevalence of aggressive driving perpetration and victimization declined with age, the factors that contributed to aggressive driving remained generally stable across the lifespan. The results suggest that efforts to reduce aggressive driving among young drivers may prove to be effective for drivers from all age groups.     

Extending end-state comfort effect: do we consider the beginning state comfort of another?

Sharing a drink or passing a tool to another person is frequently done in our daily lives. However, a second thought is rarely given about how the object should be handed; instead we pay attention to other factors (e.g., the company). This interaction (handing a tool to someone) is interesting, since it may give insight to how motor intentions are predicted. Research has demonstrated that individuals exhibit an end-state comfort effect when manipulating objects, and it is of interest to determine how this is applied to a joint-action paradigm. The purpose of this experiment was to determine if participants would anticipate the confederate's postural requirements and pass tools in a manner that allowed the confederate to have beginning state comfort and thus facilitate the motion sequence as a whole. That is, would the participant incur the cost of the movement by adopting an awkward posture to facilitate the use of the tool by the confederate? The results demonstrated that participants allowed the confederate to adopt a comfortable beginning state comfort on 100% of the trials for all the tools. However, the participants did not sacrifice end-state comfort, demonstrating that the participants were able to plan ahead to both maximize their own end-state comfort and the beginning state comfort of the confederate.     

Combinatorics and probability: six- to ten-year-olds reliably predict whether a relation will occur

Young children are able to judge which of two possibilities is more likely to occur when these possibilities are characterized by a simple property, like color (“Is it more likely to draw a red chip or a blue chip?”). Here we ask whether they can do so when the possibilities concern a relation between simple properties (“Is it more likely to draw two chips of the same color or two different colored chips?”). Three studies show that from the age of six children are able to predict the occurrence of a relation on the basis of its probability, and that from the age of nine their performance reaches adult levels. These results corroborate the theory of naive extensional reasoning, and are inconsistent with the hypothesis that children need the help of instruction to reason correctly about relations.     

On positive psychological outcomes: what helps groups with a history of conflict to forgive and reconcile with each other?

Three studies examined the roles of traditional and novel social psychological variables involved in intergroup forgiveness. Study 1 (N = 480) revealed that among the pro-Pinochet and the anti-Pinochet groups in Chile, forgiveness was predicted by ingroup identity (negatively), common ingroup identity (positively), empathy and trust (positively), and competitive victimhood (the subjective sense of having suffered more than the outgroup, negatively). Political ideology (Right vs. Left) moderated the relationship between empathy and forgiveness, trust and forgiveness, and between the latter and competitive victimhood. Study 2 (N = 309), set in the Northern Irish conflict between Protestants and Catholics, provided a replication and extension of Study 1. Finally, Study 3 (N = 155/108) examined the longitudinal relationship between forgiveness and reconciliation in Northern Ireland, revealing that forgiveness predicted reconciliation intentions. The reverse direction of this relationship was also marginally significant. Results are discussed in terms of their theoretical and practical implications.     

Liberation Psychology as the Path Toward Healing Cultural Soul Wounds

Oppression resulting in soul wounding has afflicted indigenous communities and the counseling profession. Internalized oppression has become part of oppressive practices inflicted on communities served. The authors delineate a liberation psychology that leads toward the psychological and spiritual emancipation of individual clients, communities, and the counseling profession.     

Racial Microaggressions Against Black Americans: Implications for Counseling

Racial microaggression themes were identified using a focus‐group analysis of self‐identified Black participants. Six categories of demeaning and invalidating messages reflected beliefs of White supremacy that were unintentionally conveyed by perpetrators. Implications for counselors and the counseling process are discussed.     

Spiritual disclosure between older adolescents and their mothers

This study examines the role of spiritual disclosure within older adolescent-mother relationships. Spiritual disclosure is defined as mutual disclosure of personal religious and spiritual beliefs and practices. Three hundred 18- to 20-year-old college students and 130 of their mothers reported on spiritual disclosure in their relationships. According to both parties, greater spiritual disclosure was related to higher relationship satisfaction, greater use of collaborative conflict resolution strategies, less dysfunctional communication patterns, less verbal aggression, and increased general disclosure in mother-adolescent relationships beyond global religiousness and demographics. Spiritual disclosure also predicted unique variance in collaborative conflict resolution strategies beyond these factors and general disclosure. The findings underscore the value of attending to the interpersonal dimension of religion/spirituality. More specifically, the results suggest that spiritual disclosure is an indicator of relationship quality, one that is tied to better relationship functioning, and one that merits further attention in studies of family dynamics.     

Time travel through language: Temporal shifts rapidly decrease information accessibility during reading

The present study dissociated the immediate neural costs from the subsequent neural consequences of integrating time shifts into our mental representations of events. Event-related potentials were recorded as participants read scenarios that included words referring to short temporal shifts (e.g., after one second), moderate temporal shifts (e.g., after one hour), or long temporal shifts (e.g., after one year). These words were followed by repeated noun-phrase anaphors, which are preferred as referents for information no longer in attentional focus. The N400 was measured as an index of online conceptual integration. As the discourse unfolded, the N400 was larger for long- (e.g.,year) than for short- (e.g., second) shift words. For the anaphor, the N400 was modulated in the opposite direction. Thus, the introduction of a temporal discontinuity leads to immediate neural integration costs, as well as to decreased accessibility of earlier information.
