Developmental changes in decision making under risk: The role of executive functions and reasoning abilities in 8- to 19-year-old decision makers

Previous studies have shown that children and adolescents often tend toward risky decisions despite explicit knowledge about the potential negative consequences. This phenomenon has been suggested to be associated with the immaturity of brain areas involved in cognitive control functions. Particularly, “frontal lobe functions,” such as executive functions and reasoning, mature until young adulthood and are thought to be involved in age-related changes in decision making under explicit risk conditions. We investigated 112 participants, aged 8–19 years, with a frequently used task assessing decisions under risk, the Game of Dice Task (GDT). Additionally, we administered the Modified Card Sorting Test assessing executive functioning (categorization, cognitive flexibility, and strategy maintenance) as well as the Ravens Progressive Matrices assessing reasoning. The results showed that risk taking in the GDT decreased with increasing age and this effect was not moderated by reasoning but by executive functions: Particularly, young persons with weak executive functioning showed very risky decision making. Thus, the individual maturation of executive functions, associated with areas in the prefrontal cortex, seems to be an important factor in young peoples’ behavior in risky decision-making situations.     

Effects of providing advance cues during a soccer penalty kick on the kicker's rate of success

The effect of explicitly providing goalkeeper's movement advanced cue to the kicker during a real penalty kick task was assessed. 32 expert soccer players (M age= 23.2 yr.), who were divided into four groups: an experimental group, a discovery group, a placebo group, and a control group, participated. Rate of success in the task was assessed, as well as goals, decision times, and ball flight times. Providing an advance cue significantly improved the players' rate of success relative to players without the advance cue; this difference was still present after 1 and 7 days without training. The experimental group adapted better to the time range within which the response could be effective, while the discovery group showed adaptations. Explicit instructions about the advance cues available from goalkeepers' actions before the dive during practice can improve penalty kick performance.     

Psychological care demand in clinical practice: treatment and results

With the aim of describing the usual clinical context as opposed to the academic or research context, the characteristics of patients and psychological treatments applied in a sample of 856 patients from the Clinic of Psychology of the Complutense University is analyzed. The disorders that require attention, the characteristics of the therapists and their interventions are identified. Out of the total patients, 24.3% withdrew from treatment; 68.3% of the patients who started treatment completed it with therapeutic success. 83% of patients were assessed in 4 sessions or fewer (median=4). 75.3% of patients who finished the treatment received 18 or fewer treatment sessions (median=11). The generalization of the results and their implications for professional clinical practice and for training clinical psychologists are discussed.     

Incidence of anovulatory menstrual cycles among dysmenorrheic and non-non-dysmenorrheic [corrected] women: effects on symptomatology and mood

The incidence of spontaneous anovulatory (SA) menstrual cycles among dysmenorrheic and non-dysmenorrheic women and their effects on symptomatology and mood were examined in 52 university students distributed into two groups (18 dysmenorrheic women and 34 non-dysmenorrheic women) according to the presence or absence of symptoms of primary dysmenorrhea. Women were tested in menstrual, ovulatory and premenstrual phases. In order to estimate the proportion of ovulatory and SA cycles the basal body temperature (BBT) method was used. Results indicated that the percentage of SA cycles found in dysmenorrheic women does not confirm that primary dysmenorrhea only occurs in ovulatory cycles. In addition, the ovulatory cycles did not present greater symptomatology than the anovulatory cycles in self-rating of negative affect. In fact, menstrual symptomatology was not associated with ovulatory cycles. These data confirm that primary dysmenorrhea does not only depend on the endocrine factors which regulate the menstrual cycle but also on other factors such as social or psychological ones.     

Efficacy of a group memory training method for older adults based on visualization and association techniques: A randomized,controlled trial with a placebo group

The aim of this trial has been to determine the efficacy of a group memory training method. The experimental group was compared to a placebo group (health education) or to a control group (waiting list). Forty‐five adults between the ages of 60 and 70 years (M = 66.9) were recruited by placing notices in senior citizen community centres, which encouraged people with memory problems to participate in the study. Data were collected at baseline, 1 week, and 6 months after the intervention. The efficacy of the training was evaluated by measures of objective and subjective everyday memory performance. After intervention, the experimental group participants showed an increase in objective memory performance (d = 1.95). The effect size was even higher at 6 months after intervention (d = 2.88). Further, their subjective experience related to everyday memory slips decreased (d = ?0.52). The memory training method was effective in improving everyday memory in older people with some cognitive decline. Copyright © 2009 John Wiley & Sons, Ltd.     

Group and individual change in the treatment of drug addictions: a follow-up study in therapeutic communities

The pre-post treatment change of 112 patients in two therapeutics Spanish communities is described. The Addiction Severity Index (ASI) was used at intake and at the end of the treatment program. Results of the treatment program were evaluated by applying composite scores (CS) of the ASI, and the evolution of each patient was evaluated using the Reliable Change Index (RCI). 69.7% of the sample completed treatment, and 30.3% dropped out prematurely. At intake, the percentage of people who could improve in the different areas of the ASI ranged between 35.1% for alcohol consumption and 95.3% for family relationships. At the follow-up, the percentage of subjects who showed significant statistical improvements in the different areas varied between 7.9% in family relations and 66.7% in alcohol consumption. The percentage of patients who deteriorated was less than 10% for all variables. Implications for further research and clinical practice are commented upon.

The contribution of prefixes to morphological processing of Spanish words

Three series of priming experiments were conducted to probe the morphological and phonological contributions to visual word recognition in Spanish. Prefixed, e.g., INCAPAZ (incapable), and pseudoprefixed, e.g., INDUSTRIA (industry) target words were presented for recognition following a prefixed, e.g., infeliz (unhappy), or pseudoprefixed, e.g., insulto (insult), prime starting with the same syllable as the target, at masked short or long stimulus onset asynchronies (SOAs). At long SOAs the recognition of prefixed targets was facilitated by prefixed primes and inhibited by pseudoprefixed ones, whereas both prefixed and pseudoprefixed primes facilitated the recognition at short SOAs. In contrast, the recognition of pseudoprefixed targets was unaffected by the kind of prime presented, even when we used pairs of words overlapping in syllables that cannot be prefixes in Spanish. These results support a special status for morphological elements in access to meaning in reading.     

Social referencing in infants of mothers with symptoms of depression

The present study examined the acquisition of social referencing skills in infants of mothers with symptoms of depression (n = 44). We aimed to determine if a short discrimination training could facilitate infants’ social referencing. Mothers were instructed to pose either joyful or fearful facial expressions to cue infants’ approach/avoidance responses toward an ambiguous object. Maternal expressions were correlated with pleasant or unpleasant events occurring after the infant's response. The results showed that after the intervention, infants looked at their mothers more frequently and reached or avoided the ambiguous object based on the preceding maternal expression. The results suggest that discrimination training procedures can establish social referencing in infants of mothers with symptoms of depression.     

Inferentialism,degrees of commitment,and ampliative reasoning

Our purpose in this paper is to contribute to a practice-based characterization of scientific inference. We want to explore whether Brandom’s pragmatist–inferentialist framework can suitably accommodate several types of ampliative inference common in scientific reasoning and explanation (probabilistic reasoning, abduction and idealisation). First, we argue that Brandom’s view of induction in terms of merely permissive inferences is inadequate; in order to overcome the shortcoming of Brandom’s proposal, we put forward an alternative conception of inductive, probabilistic reasoning by appeal to the notion of degrees of commitment. Moreover, we examine the sorts of inferential commitments operative in other types of ampliative inferences, such as abduction or reasoning involving idealizations and assumptions. We suggest that agents engaging in these forms of reasoning often undertake restricted inferential commitments, whose scope and reach are more limited that in the case of the commitments associated with full beliefs.
