Engaging reluctant adolescents in family therapy: an exploratory study of in‐session processes of change

Informed by a trans‐theoretical model of the therapeutic alliance in conjoint family therapy, this exploratory study was the initial stage in a task analysis of critical shifts in adolescent engagement. Specifically, we compared sessions in which a resistant adolescent either did or did not shift from negative to positive engagement during the session. Two successful and two unsuccessful change events were selected from an archival data set based on SOFTA ratings of the therapeutic alliance. The results suggested that one parent element (support) and five therapist elements (structuring therapeutic conversations, fostering autonomy, building systemic awareness, rolling with resistance and understanding the adolescent's subjective experience) seemed critical for successfully facilitating adolescent engagement. The qualitative results were informed by the adolescent's self‐reported target complaints pretreatment, which suggested varying reasons for the teenagers’ active or passive disengagement. Implications for practice and recommendations for future research are offered to continue this line of inquiry.     

Impaired executive functions in subjects with frequent nightmares as reflected by performance in different neuropsychological tasks

Nightmare disorder is a prevalent parasomnia characterized by vivid and highly unpleasant dream experiences during night time sleep. The neural background of disturbed dreaming was proposed to be associated with impaired prefrontal and fronto-limbic functioning during REM sleep. We hypothesized that the impaired prefrontal and fronto-limbic functioning in subjects with frequent nightmares would be reflected at the behavioral level during waking tasks as well. 35-35 Subjects with frequent nightmares and matched controls participated in Study 1, involving an Emotional Go/NoGo, an Emotional Stroop task, and a Verbal Fluency task. Nightmare subjects exhibited longer reaction times in the Emotional Go/NoGo and Emotional Stroop tasks. Moreover, they committed more perseveration errors and showed less fluent word generation in the Verbal Fluency task. Nightmare subjects showed an overall slowing irrespective of the valence of the stimuli. While the effects of sleep quality and waking anxiety were associated to these deficits in some cases, these factors could not solely explain the difference between the two groups. In Study 2, 17 subjects with frequent nightmares and 18 controls were compared by a Color-word and an Emotional, block design Stroop task in order to avoid the slow effects of emotional interference potentially caused by previous items. Nightmare subjects were characterized by an overall slowing in the Emotional Stroop task, irrespective of the valence of the stimuli. In the Color-word Stroop task, nightmare subjects were not significantly slower in comparison with controls. Our results suggest that individuals with frequent nightmares are impaired in executive tasks involving the suppression of task-irrelevant semantic representations.     

Costs and Benefits of Autonomy When Learning a Task: An Experimental Approach

ABSTRACT

Previous findings suggested that the positive relationship between autonomy and learning outcomes (such as improved task performance) only holds up until a certain optimum level of autonomy has been reached. This assumption was investigated in an experimental study where 95 participants had to learn a computer task. During the learning phase, we manipulated autonomy, distinguishing among no, moderate, and full autonomy. The results revealed that, when learning a task, having autonomy is preferred to having no autonomy. However, increases in autonomy beyond a certain level (i.e., full versus moderate autonomy) will not yield additional advantages regarding the motivation to learn and learning outcomes, and may have disadvantages in terms of learning efficiency.     

Infant Contingency Learning in Different Cultural Contexts

Three‐month‐old Cameroonian Nso farmer and German middle‐class infants were compared regarding learning and retention in a computerized mobile task. Infants achieving a preset learning criterion during reinforcement were tested for immediate and long‐term retention measured in terms of an increased response rate after reinforcement and after a 24‐h delay compared with baseline. It was hypothesized that infants from both cultural communities would acquire the contingency between own motion and mobile movement, as they similarly experience contingent responses in social interactions. Nso infants were assumed to show a higher learning rate related to their advanced gross motor development, whereas German infants were expected to show a higher baseline because of culture‐typical motor handling promoting a high level of activity (i.e. lying supine). Results showed immediate and long‐term retention in infants from both cultural contexts, as well as a higher baseline for German infants. Although the learning rate was higher for Cameroonian infants, logistic regression revealed that learning was not related to gross motor development but depended on the level of baseline response. Thus, contingency learning was shown in different cultural environments, and the level of baseline activity coined by culture‐specific motor handling turned out to influence learning within the mobile task.

Data-driven sequence learning or search: What are the prerequisites for the generation of explicit sequence knowledge?

In incidental sequence learning situations, there is often a number of participants who can report the task-inherent sequential regularity after training. Two kinds of mechanisms for the generation of this explicit knowledge have been proposed in the literature. First, a sequence representation may become explicit when its strength reaches a certain level (Cleeremans, 2006), and secondly, explicit knowledge may emerge as the result of a search process that is triggered by unexpected events that occur during task processing and require an explanation (the unexpected-event hypothesis; Haider & Frensch, 2009). Our study aimed at systematically exploring the contribution of both mechanisms to the generation of explicit sequence knowledge in an incidental learning situation. We varied the amount of specific sequence training and inserted unexpected events into a 6-choice serial reaction time task. Results support the unexpected-event view, as the generation of explicit sequence knowledge could not be predicted by the representation strength acquired through implicit sequence learning. Rather sequence detection turned out to be more likely when participants were shifted to the fixed repeating sequence after training than when practicing one and the same fixed sequence without interruption. The behavioral effects of representation strength appear to be related to the effectiveness of unexpected changes in performance as triggers of a controlled search.     

Stimulus-dependent modulation of perceptual and motor learning in a serial reaction time task

In two experiments, we investigated the impact of spatial attributes on the representation acquired during a serial reaction time task. Two sequences were used, in which structural regularities occurred either in the horizontal or in the vertical locations of successive stimuli. After training with the dominant hand, participants were required to respond with the non-dominant hand to either the original sequence or to a mirror-ordered version of the original sequence that required finger movements homologous to those used during training. We observed that a difference in reaction times between the two transfer conditions was smaller in the vertical sequence than in the horizontal sequence. This pattern of results was independent of whether three fingers (Experiment 1) were used or only one finger (Experiment 2) was used for responding. This result suggests that perceptual and motor learning mechanisms may be weighted differently depending on the context in which the stimulus is presented.     

Should inter-collegiate football be eliminated? Assessing the arguments philosophically

Recently, there have been discussions about whether or not inter-collegiate football should be eliminated in the US. This article philosophically assesses the arguments for its elimination as well as the arguments proffered against its elimination. While a variety of arguments are discussed, a new one is brought into the foray of philosophical investigation, one that combines the unfairness and economic arguments: the health care and medical costs to others argument. It is believed that this argument is sufficient to justify the elimination of inter-collegiate football.     

不同认知方式对词—面孔任务Stroop效应的影响

该研究采用词—面孔Stroop任务,以76名大学生为被试,探讨了不同认知方式（场独立、场依存）对情绪冲突Stroop效应的影响。结果发现：（1）情绪冲突的Stroop效应显著,即,在词—面孔Stroop任务中,当词和面孔的情绪效价一致时,被试的反应时更短,正确率更高。（2）认知方式对情绪冲突Stroop任务的影响显著,表现为无论是一致还是不一致条件下,场独立者比场依存者的反应时都更短。（3）场依存者的情绪冲突Stroop效应更大,表现为其在词—面孔情绪效价一致和不一致条件下的反应时差异更大。

Judgment Difficulty and the Moral Intensity of Unethical Acts: A Cognitive Response Analysis of Dual Process Ethical Judgment Formation

This study analyzes cognitive responses to explore a dual processing perspective of ethical judgment formation. Specifically, the study investigates how two factors, judgment task difficulty and moral intensity, influence the extent of deontological and teleological processing and their effects on ethical judgments. A single experiment on 110 undergraduate research participants found that judgment task difficulty affected the extent of deontological and teleological processing. Although moral intensity affected ethical judgments, it did not produce effects on either deontological or teleological cognitive responses. Results did not support the hypotheses that deontological and teleological cognitive responses would mediate the relationships between the experimental factors and ethical judgments. Overall, the results support continued research of factors that affect the nature of information processing in ethical decision situations and the use of cognitive response analysis as a tool for conducting this research.
