On the peculiarity of simple reaction time

Two experiments are reported in which high-compatibility reaction time (RT) tasks were performed with, and without, a concurrent secondary task. In both experiments, the secondary task interfered to a greater extent with simple RT than with choice RT. In fact, the effect of adding a secondary task was to eliminate the advantage of simple RT over two-alternative-choice RT. Previous studies of this phenomenon employed a task in which subjects raised a finger when it received tactile stimulation, while engaging in continuous reading aloud. The present experiments show that the effect can be obtained using a different stimulus modality (vision) as well as other responses (vocal) and secondary tasks (shadowing, auditory step-tracking). The paradigm provides a means of isolating preparatory processes that are peculiar to the simple RT task.     

Children's understanding and production of verbal irony in family conversations

This study examined how children use and understand various forms of irony (sarcasm, hyperbole, understatement, and rhetorical questions) in the context of naturalistic positive and negative family conversations in the home. Instances of ironic language in conversations between mothers, fathers, and their two children (M_ages=6.33 and 4.39 years) were recorded during six 90‐min observations for each of 39 families. Children's responses to others' ironic utterances were coded for their understanding of meaning and conversational function. Mothers were especially likely to ask rhetorical questions and to use ironic language in conflictual contexts. In contrast, fathers used hyperbole and understatement as frequently as rhetorical questions, and employed ironic language in both positive and conflictual contexts. Children also showed evidence of a nascent ability to use ironic language, especially hyperbole and rhetorical questions. Family members used rhetorical questions and understatement proportionately more often in a negative interaction context. Finally, older siblings understood irony better than younger siblings, and both children's responses revealed some understanding of ironic language, particularly sarcasm and rhetorical questions. Overall, the results suggest that family conversations in the home may be one important context for the development of children's use and understanding of ironic language.     

Effects of provision and receipt of social support on adjustment to laparoscopic radical prostatectomy

Radical prostatectomy has a negative impact on prostate cancer patients' health-related quality of life (HRQoL). Social support may help patients adjust to their situation after surgery. We investigated patients' accounts of received social support as well as their spouses' accounts of provided social support as predictors of patients' HRQoL 6 months after surgery. Moreover, we tested whether patients with lower HRQoL at 2 weeks after surgery had the most benefit from spousal support. A total of 77 patients (M = 61.57 years, SD = 6.03) and their spouses (M = 58.46 years, SD = 7.52) completed questionnaires at 2 weeks and 6 months after laparoscopic radical prostatectomy. Received social support, spousal provided social support, and HRQoL were assessed 2 weeks after surgery, and HRQoL was assessed again 6 months later. Patients with lower HRQoL at 2 weeks after surgery benefited more from the receipt and their partners' provision of support in terms of HRQoL 6 months later than patients with a higher HRQoL at the beginning. Assessing patients' HRQoL might be one method to identify those individuals who are in special need of support from their spouses.     

Evidence for recovery of fear following immediate extinction in rats and humans

Fear responses can be eliminated through extinction, a procedure involving the presentation of fear-eliciting stimuli without aversive outcomes. Extinction is believed to be mediated by new inhibitory learning that acts to suppress fear expression without erasing the original memory trace. This hypothesis is supported mainly by behavioral data demonstrating that fear can recover following extinction. However, a recent report by Myers and coworkers suggests that extinction conducted immediately after fear learning may erase or prevent the consolidation of the fear memory trace. Since extinction is a major component of nearly all behavioral therapies for human fear disorders, this finding supports the notion that therapeutic intervention beginning very soon after a traumatic event will be more efficacious. Given the importance of this issue, and the controversy regarding immediate versus delayed therapeutic interventions, we examined two fear recovery phenomena in both rats and humans: spontaneous recovery (SR) and reinstatement. We found evidence for SR and reinstatement in both rats and humans even when extinction was conducted immediately after fear learning. Thus, our data do not support the hypothesis that immediate extinction erases the original memory trace, nor do they suggest that a close temporal proximity of therapeutic intervention to the traumatic event might be advantageous.     

Extinction and spontaneous recovery of a conditioned flavor preference based on calories

After rats were conditioned to prefer a flavor (CS+) paired with sucrose over another flavor (CS−) paired with saccharin, this conditioned flavor preference was extinguished by presenting the CS+ flavor without sucrose. These results were replicated in a second experiment in which spontaneous recovery of the extinguished flavor preference was demonstrated 7, 14, and 21 days after the extinction test. This is the first clear demonstration of the extinction and spontaneous recovery of a conditioned flavor preference based on calories. The implications of these results for our understanding of the mechanism underlying the conditioning of flavor preferences are explored.     

Parental Cognitive Errors Mediate Parental Psychopathology and Ratings of Child Inattention

We investigate the Depression‐Distortion Hypothesis in a sample of 199 school‐aged children with ADHD‐Predominantly Inattentive presentation (ADHD‐I) by examining relations and cross‐sectional mediational pathways between parental characteristics (i.e., levels of parental depressive and ADHD symptoms) and parental ratings of child problem behavior (inattention, sluggish cognitive tempo, and functional impairment) via parental cognitive errors. Results demonstrated a positive association between parental factors and parental ratings of inattention, as well as a mediational pathway between parental depressive and ADHD symptoms and parental ratings of inattention via parental cognitive errors. Specifically, higher levels of parental depressive and ADHD symptoms predicted higher levels of cognitive errors, which in turn predicted higher parental ratings of inattention. Findings provide evidence for core tenets of the Depression‐Distortion Hypothesis, which state that parents with high rates of psychopathology hold negative schemas for their child's behavior and subsequently, report their child's behavior as more severe.     

The Metaphysical Consequences of Counterfactual Skepticism

A series of recent arguments purport to show that most counterfactuals of the form if A had happened then C would have happened are not true. These arguments pose a challenge to those of us who think that counterfactual discourse is a useful part of ordinary conversation, of philosophical reasoning, and of scientific inquiry. Either we find a way to revise the semantics for counterfactuals in order to avoid these arguments, or we find a way to ensure that the relevant counterfactuals, while not true, are still assertible. I argue that regardless of which of these two strategies we choose, the natural ways of implementing these strategies all share a surprising consequence: they commit us to a particular metaphysical view about chance.     

FATHER–CHILD PLAY DURING THE PRESCHOOL YEARS AND CHILD INTERNALIZING BEHAVIORS: BETWEEN ROBUSTNESS AND VULNERABILITY

Play observations with a total of 400 toddlers and preschoolers were videotaped and rated for Intensity and Quality of play with their parents. Parents were asked about perceived stress and personality characteristics (Big 5). Child's motor, cognitive skills, temperament, and internalizing behaviors were assessed. Study 1 investigated the robustness of play across child age and gender, and examined differences between fathers and mothers. Study 2 explored the vulnerability of play with fathers of children born preterm (PT‐fathers) and fathers who had experienced adverse childhoods (AC‐fathers). Study 3 investigated child internalizing behaviors. Intensity of play was maintained almost independently of child age and gender. It was similar for AC‐ and PT‐fathers, and similar to maternal Intensity. In contrast, paternal Quality of play was higher with boys and independent of fathers’ personality and perceived parenting stress whereas maternal Quality of play was higher with girls and linked to mothers’ perceived parenting competence, acceptability of the child, and neuroticism. AC‐fathers scored significantly low on Quality, as did PT‐fathers, but the Quality of their play became better with growing child age, birth weight, and cognitive (but not motor and temperament) scores. Finally, child internalizing behaviors were negatively related to paternal Quality of play.     

Academic Cheating in Mathematics Classes: A Motivational Perspective

We investigated the frequency of secondary school students’ self-reported cheating in mathematics and relationships between cheating and motivational beliefs, as well as neutralizing attitudes. Two types of cheating were examined: active cheating, which is aimed to increase a person’s own success, and second-party cheating, aimed to help other students achieve success. Students use second-party cheating very often and more than active cheating. Motivational beliefs are significantly related to active cheating but uncorrelated with second-party cheating. Thus, although active and second-party cheating are both classified as dishonest acts, they do not have the same motivational mechanisms in their background.
