How do students improve their value-based learning with task experience?

When learning items that vary in reward, students improve their scores (i.e., earned reward) with task experience. In four experiments, we examined whether such improvements arise from better selective encoding of items that would earn more (vs. less) reward. Participants studied and recalled words across multiple study-test trials. On each trial, 12 words were slated with different values (typically from 1 to 12), and participants earned the point value assigned to a given word if it was correctly recalled. In all experiments, participants earned more points across the first two trials. In Experiment 1, participants either self-paced their study or had experimenter-paced study and in Experiment 2, some participants were penalised for each second spent during study. Improvements in points earned were related to increases in overall recall but not to selective encoding. In Experiment 3, some participants were given value-emphasised instructions, yet they did not demonstrate selective encoding. In Experiment 4, we used a larger range of point values, but selective encoding still did not account for the improvement in point scores across lists. These results suggest that metacognitively-driven selective encoding is not necessary to observe improvements in value-based learning.     

The selective power of causality on memory errors

We tested the influence of causal links on the production of memory errors in a misinformation paradigm. Participants studied a set of statements about a person, which were presented as either individual statements or pairs of causally linked statements. Participants were then provided with causally plausible and causally implausible misinformation. We hypothesised that studying information connected with causal links would promote representing information in a more abstract manner. As such, we predicted that causal information would not provide an overall protection against memory errors, but rather would preferentially help in the rejection of misinformation that was causally implausible, given the learned causal links. In two experiments, we measured whether the causal linkage of information would be generally protective against all memory errors or only selectively protective against certain types of memory errors. Causal links helped participants reject implausible memory lures, but did not protect against plausible lures. Our results suggest that causal information may promote an abstract storage of information that helps prevent only specific types of memory errors.     

When the face fits: Recognition of celebrities from matching and mismatching faces and voices

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face–voice pairs in which the face and voice were co-presented and were either “matched” (same person), “related” (two highly associated people), or “mismatched” (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.     

Towards a Marine Mindset: Visiting an Aquarium Can Improve Attitudes and Intentions Regarding Marine Sustainability

ABSTRACT

The oceans are crucial for human survival, yet they are under serious threat from humans, for example through overfishing and poor waste management. We investigated two questions. First, does a leisure visit to an aquarium improve visitor attitudes and intentions towards marine sustainability, specifically regarding overfishing and pollution? Second, does an information booklet handed out in addition to the visit have additional measurable impact? Aquarium visitors (n = 104) completed a questionnaire on marine sustainability attitudes and behavioral intentions before and after their visit. Half of the visitors also were given informational materials that offered behavioral solutions to the problem of overfishing. The aquarium visit significantly improved visitors’ overall attitudes and intentions. The information booklet additionally improved intentions significantly, but not attitudes. These findings show that a visit to an aquarium can help individuals develop what we term a marine mindset, a state of readiness to address marine sustainability issues. Implications, limitations, and ideas for further research are discussed.     

Emotional Expression During Autobiographical Narratives as a Function of Aging: Support for the Socioemotional Selectivity Theory

People communicate personal stories in very different ways. These variations in communication patterns may be affected by many variables, particularly age. Socioemotional Selectivity Theory (SST) predicts young adults are focused on information gathering to function in society, whereas older adults become increasingly motivated to regulate emotions and pursue emotionally salient yet stable goals and activities. What is not understood is whether communication patterns reflect this developmental transition. Younger and older adults (n = 120) completed negative and positive autobiographical narratives that were analyzed with a Linguistic Inquiry and Word Count Program. Results indicated that younger adults utilized more affective words in general, including more positive, negative, and anxious words during autobiographical narratives. In the positive autobiographical task, older adults used a higher percentage of “family” words, whereas in the negative autobiographical task, younger adults more frequently utilized “friend” words. In terms of pronoun use, there was evidence for increased second and third person pronouns among older adults. Results related to affective, social, and pronoun word use are largely supportive of SST. However, other important findings that were not predicted were noteworthy, including the finding that results varied as a function of narrative valence.     

An Acceptance-Based Behavioral Therapy for Individuals With Generalized Anxiety Disorder

In response to clinical observations and research findings that individuals with generalized anxiety disorder are reactive to their internal experiences, avoid and suppress painful emotions, thoughts, and sensations, and limit their involvement in meaningful activities, an Acceptance Based Behavioral Therapy (ABBT) was developed to specifically target these responses. ABBT incorporates acceptance and mindfulness strategies with more traditional behavior therapy techniques. Specifically, ABBT uses mindfulness and acceptance approaches as an alternate response to the rigid, avoidant responses characteristic of GAD. Likewise, therapy focuses on identifying and enacting behaviors that are congruent with what is personally meaningful to the client rather than engaging in actions that are motivated by avoidance of anxiety. This article provides a case conceptualization from an ABBT perspective for “William,” the composite client presented in Robichaud (2013a--this issue). The article goes on to demonstrate how an ABBT approach to treatment may unfold session-by-session for “William.”     

Psychological Treatment Improves Hemoglobin A1c Outcomes in Adolescents with Type 1 Diabetes Mellitus

Adolescents diagnosed with Type 1 Diabetes Mellitus often exhibit reduced adherence to their medical regimen and poor glycemic control. A retrospective study examined longitudinal hemoglobin A1c (HgbA1c) outcomes for adolescent patients referred to the psychology service embedded within an endocrinology clinic. Three patient groups were examined: (1) Treatment: 59 adolescents referred who engaged in psychotherapy; (2) No Treatment: 40 adolescents referred yet failed to initiate psychotherapy; (3) Control: 58 adolescents not referred for treatment and matched on demographics to the two treatment groups. Over 1 year, the Treatment group had a sustained decrease in HgbA1c while the No Treatment and Control groups had an overall increase in HgbA1c. At study end, the Treatment group had HgbA1c values that were not significantly different from patients who were not considered in need of psychological treatment (Control). Adolescents that utilized the pediatric psychology service saw decreased HgbA1c values over time.     

Classroom Changes in ADHD Symptoms Following Clinic-Based Behavior Therapy

This study examined classroom behavioral outcomes for children with Attention-Deficit/Hyperactivity Disorder (ADHD) following their participation in a manualized, 10-week intervention called Family Skills Training for ADHD-Related Symptoms (Family STARS). Family STARS combined behavioral parent training (BPT) and child-focused behavioral activation therapy (CBAT). Participants were children ages 7–10 diagnosed with ADHD-Combined Type. Pre- and post-treatment teacher ratings of ADHD symptoms were compared using a single group, within-subjects research design. Intervention effectiveness was analyzed using paired-samples t-tests. Results indicated statistically significant classroom improvements for externalizing behaviors and attention problems with medium and large main effects (respectively) for the intervention. Possible implications for combining CBAT with BPT for the treatment of ADHD are discussed as well as the relevance of these results for improving the effectiveness and portability of empirically supported interventions.     

Parental Coping in the Neonatal Intensive Care Unit

Fifty-six mothers of premature infants who participated in a study to reduce symptoms of posttraumatic stress disorder (PTSD) completed the Brief COPE, a self-report inventory of coping mechanisms, the Stanford Acute Stress Reaction Questionnaire to assess acute stress disorder (ASD) and the Davidson Trauma Scale to assess PTSD. 18 % of mothers had baseline ASD while 30 % of mothers met the criteria for PTSD at the 1-month follow-up. Dysfunctional coping as measured by the Brief COPE was positively associated with elevated risk of PTSD in these mothers (RR = 1.09, 95 % CI 1.02–1.15; p = .008). Maternal education was positively associated with PTSD; each year increase in education was associated with a 17 % increase in the relative risk of PTSD at 1 month follow-up (RR = 1.17, 95 % CI 1.02–1.35; p = .03). Results suggest that dysfunctional coping is an important issue to consider in the development of PTSD in parents of premature infants.
