Cross-modal links in exogenous covert spatial orienting between touch, audition, and vision

Three experiments investigated cross-modal links between touch, audition, and vision in the control of covert exogenous orienting. In the first two experiments, participants made speeded discrimination responses (continuous vs. pulsed) for tactile targets presented randomly to the index finger of either hand. Targets were preceded at a variable stimulus onset asynchrony (150,200, or 300 msec) by a spatially uninformative cue that was either auditory (Experiment 1) or visual (Experiment 2) on the same or opposite side as the tactile target. Tactile discriminations were more rapid and accurate when cue and target occurred on the same side, revealing cross-modal covert orienting. In Experiment 3, spatially uninformative tactile cues were presented prior to randomly intermingled auditory and visual targets requiring an elevation discrimination response (up vs. down). Responses were significantly faster for targets in both modalities when presented ipsilateral to the tactile cue. These findings demonstrate that the peripheral presentation of spatially uninforrnative auditory and visual cues produces cross-modal orienting that affects touch, and that tactile cues can also produce cross-modal covert orienting that affects audition and vision.     

Auditory and audiovisual inhibition of return

Two experiments examined any inhibition-of-return (IOR) effects from auditory cues and from preceding auditory targets upon reaction times (RTs) for detecting subsequent auditory targets. Auditory RT was delayed if the preceding auditory cue was on the same side as the target, but was unaffected by the location of the auditorytarget from the preceding trial, suggesting that response inhibition for the cue may have produced its effects. By contrast, visual detection RT was inhibited by the ipsilateral presentation of a visual target on the preceding trial. In a third experiment, targets could be unpredictably auditory or visual, and no peripheral cues intervened. Both auditory and visual detection RTs were now delayed following an ipsilateral versus contralateral target in either modality on the preceding trial, even when eye position was monitored to ensure central fixation throughout. These data suggest that auditory target—target IOR arises only when target modality is unpredictable. They also provide the first unequivocal evidence for cross-modal IOR, since, unlike other recent studies (e.g., Reuter-Lorenz, Jha, & Rosenquist, 1996; Tassinari & Berlucchi, 1995; Tassinari & Campara, 1996), the present cross-modal effects cannot be explained in terms of response inhibition for the cue. The results are discussed in relation to neurophysiological studies and audiovisual links in saccade programming.     

Generalized expectancies for negative mood regulation predict change in anxiety and depression among college students

Negative mood regulation (NMR) expectancies, or the beliefs held by individuals that, when faced with various manifestations of stress and negative affect, they can successfully cope with such mood states, have proven to be a most useful construct in the context of better understanding self-regulatory processes. In the present prospective study, we examined the predictive utility of NMR expectancies with respect to its ability to predict residual change in both depressive and anxiety symptoms over an 8-week timeframe in a sample of 322 college students. Initial correlational analyses revealed that, as anticipated, NMR expectancies were negatively correlated with depressive and anxiety symptomatology, as well as with maladaptive coping style. Conversely, NMR expectancies were positively associated with self-reported adaptive coping. A series of hierarchical regression analyses revealed that, even when controlling for age, sex, baseline levels of affective distress (depression or anxiety), and coping styles, NMR expectancies predicted change in both depressive and anxiety symptomatology. Implications of the findings pertinent to theory building and testing are discussed.     

Does social exclusion motivate interpersonal reconnection? Resolving the "porcupine problem"

Evidence from 6 experiments supports the social reconnection hypothesis, which posits that the experience of social exclusion increases the motivation to forge social bonds with new sources of potential affiliation. Threat of social exclusion led participants to express greater interest in making new friends, to increase their desire to work with others, to form more positive impressions of novel social targets, and to assign greater rewards to new interaction partners. Findings also suggest potential boundary conditions to the social reconnection hypothesis. Excluded individuals did not seem to seek reconnection with the specific perpetrators of exclusion or with novel partners with whom no face-to-face interaction was anticipated. Furthermore, fear of negative evaluation moderated responses to exclusion such that participants low in fear of negative evaluation responded to new interaction partners in an affiliative fashion, whereas participants high in fear of negative evaluation did not.     

Thomas Wolfe: Study of a Wanderer

Thomas Wolfe was an American novelist who in his short and tragic life (1900-1939) was preoccupied with themes of lost youth, memory, transience and an insatiable wandering. Wolfe was preoccupied with what I have seen, felt and thought. He was a wanderer who in his brief life made seven voyages to Europe and compulsively explored that continent. He would never own a home or a piece of land. He rarely lived in an apartment for more than a year and more commonly for just a few months. The purpose of this paper is to explore the meaning of Wolfe's tormented wandering and his endless searching. It will be my thesis that Wolfe demonstrated an inability to mourn. His writings are an attempt to recapture his past and to restore a lost world. Emphasis will be placed on themes of loss and mourning, insatiable hunger and desire, preoccupation with transience and death, and a search for that which was lost.     

Adaptation, teleology, and selection by consequences

This paper presents and defends the view that reinforcement and natural selection are selection processes, that selection processes are neither mechanistic nor teleological, and that mentalistic and vitalistic processes are teleological but not mechanistic. The differences between these types of processes are described and used in discussing the conceptual and methodological significance of “selection type theories” and B. F. Skinner's radical behaviorist view that “operant behavior is the field of intention, purpose, and expectation. It deals with that field precisely as the theory of evolution has dealt with another kind of purpose” (1986, p. 716). The antimentalism of radical behaviorism emerges as a post-Darwinian extension of Francis Bacon's (and Galileo's) influential view that “[the introduction of final causes] rather corrupts than advances the sciences” (Bacon, 1905, p. 302).     

Barriers to Adherence to Child Assessment Recommendations

We conducted a one-year follow-up study of child psychoeducational assessment cases to examine whether and how the assessments were helpful to families. The current report focuses on parents’ views of their child’s assessment as well as the parents’ adherence with the written recommendations provided to them following their child’s assessment. Fifty-one of 72 eligible parents whose child received an assessment in an urban, Midwest university clinic participated. Based on semistructured interviews with the parents about the assessment recommendations, we grouped the recommendations and any barriers to adherence the parents mentioned into categories, and we also rated the clarity and complexity of the recommendations. Findings showed that, on average, parents identified the assessment process as useful and attempted or fully adhered to 71.5?% of recommendations. Parents reported the lowest adherence when referrals were recommended for their child to be seen by other professionals such as a pediatrician or psychiatrist; and they cited significantly more stigma barriers for recommendations to seek counseling/therapy or psychotropic medication than for recommendations pertaining to changes at home or school. Higher parental compliance was predicted by a combination of parents reporting fewer barriers and receiving more home based recommendations. The results support the utility of psychological assessments from parents’ perspectives and suggest ways in which psychologists may increase the likelihood that parents will adhere to their recommendations.     

Spirituality and psychological pain: the mediating role of social support

Spirituality is a multifaceted construct, and often studied as a one- or two-dimensional variable. Recent work has resulted in the development of the RiTE model of spirituality. While preliminarily supported as a useful approach to measuring spirituality, little is known regarding its associations with other outcomes. Past studies have shown inverse associations between spirituality and psychological distress, which appears to be partially a function of social support derived from spiritual beliefs or practices. As such, the present study tested the relationship between the RiTE dimensions and psychache as mediated by multiple types of social support. Parallel mediation results from an undergraduate sample (N?=?1994) showed that all three RiTE dimensions were indirectly associated with psychache via multiple forms of social support. Ritualistic and existential spirituality also displayed direct associations with psychache. Implications of these findings are discussed in the context of past literature, applicable theoretical constructs, and treatment considerations.     

Are high school students accurate or clueless in estimating substance use among peers?

The purpose of this study was to assess adolescents' estimations of the prevalence of alcohol and other drug use and to examine the consistency between these estimations and reported use. A survey was administered to 223 students in three northwestern U.S. high schools. Results showed that students in each of the three high schools grossly overestimated the prevalence of substance use when compared to self-reports of use. Still, students were not entirely clueless about the relative normativeness of substance use when comparing estimates and rates of use among the three schools. The school with the highest estimated prevalence of a particular substance use behavior generally also had the highest self-reported use of that same substance. These findings imply the need for high school personnel to provide students with accurate information about the actual prevalence of substance use within each school.
