Motivated semantic control: Exploring the effects of extrinsic reward and self-reference on semantic retrieval in semantic aphasia

Recent insights show that increased motivation can benefit executive control, but this effect has not been explored in relation to semantic cognition. Patients with deficits of controlled semantic retrieval in the context of semantic aphasia (SA) after stroke may benefit from this approach since ‘semantic control’ is considered an executive process. Deficits in this domain are partially distinct from the domain-general deficits of cognitive control. We assessed the effect of both extrinsic and intrinsic motivation in healthy controls and SA patients. Experiment 1 manipulated extrinsic reward using high or low levels of points for correct responses during a semantic association task. Experiment 2 manipulated the intrinsic value of items using self-reference, allocating pictures of items to the participant (‘self’) or researcher (‘other’) in a shopping game before participants retrieved their semantic associations. These experiments revealed that patients, but not controls, showed better performance when given an extrinsic reward, consistent with the view that increased external motivation may help ameliorate patients’ semantic control deficits. However, while self-reference was associated with better episodic memory, there was no effect on semantic retrieval. We conclude that semantic control deficits can be reduced when extrinsic rewards are anticipated; this enhanced motivational state is expected to support proactive control, for example, through the maintenance of task representations. It may be possible to harness this modulatory impact of reward to combat the control demands of semantic tasks in SA patients.     

Altering Impulsive Decision Making With an Acceptance-Based Procedure

Delay discounting is one facet of impulsive decision making and involves subjectively devaluing a delayed outcome. Steeply discounting delayed rewards is correlated with substance abuse and other problematic behaviors. To the extent that steep delay discounting underlies these clinical disorders, it would be advantageous to find psychosocial avenues for reducing delay discounting. Acceptance-based interventions may prove useful as they may help to decrease the distress that arises while waiting for a delayed outcome. The current study was conducted to determine if a 60–90 minute acceptance-based training would change delay discounting rates among 30 undergraduate university students in comparison to a waitlist control. Measures given at pre- and posttraining included a hypothetical monetary delay discounting task, the Acceptance and Action Questionnaire-II (AAQ-II), and the Distress Tolerance Scale. Those assigned to the treatment group decreased their discounting of delayed money, but not distress intolerance or psychological inflexibility when compared to the waitlist control group. After the waiting period, the control group received the intervention. Combining all participants’ pre- to posttreatment data, the acceptance-based treatment significantly decreased discounting of monetary rewards and increased distress tolerance. The difference in AAQ-II approached significance. Acceptance-based treatments may be a worthwhile option for decreasing delay discounting rates and, consequently, affecting the choices that underlie addiction and other problematic behaviors.     

Subjective Well-Being Predictors of Academic Citizenship Behavior

Two studies tested the hypothesis that SWB predicts unique variance in academic citizenship attitudes, even while accounting for personality traits. In Study 1, participants (n?=?2,566) completed an online questionnaire assessing their positive and negative affect, ACBs and personality. The results indicated that positive affect predicted consideration, civic virtue, and conscientiousness, whereas negative affect predicted citizenship conscientiousness and sportsmanship while controlling for personality. In Study 2, participants (n?=?260) completed measures of life satisfaction, ACBs and personality. The results showed that life satisfaction predicted all ACBs while controlling for personality. Based on these results, it can be concluded that SWB is an important predictor of ACBs. Implications for the selection of student aids in academic settings are discussed.     

Religious Schools,Home Schools,and the Timing of First Marriage and First Birth

The timing of individuals’ family formation is important for a number of socioeconomic and health outcomes. We examine the influence of religious schools and home schools on the timing of first marriage and first birth using data from the Cardus Education Study Graduate Survey (N = 1,496). Our results from life tables and event-history regression models show that, on average, graduates of evangelical Protestant schools—but not Catholic school or homeschool graduates—have earlier marriages and births than public school graduates. Catholic school students have later first births on average than public school graduates. Models interacting schooling type with age and age-squared suggest that evangelical schoolers’ higher odds of marriage stem from higher odds of marrying at ages 21–30, and their higher odds of first birth stem from higher odds of births from ages 25–34. Catholic school and nonreligious private school students also have higher odds of marrying in the mid-20s and early-30s than do public school students. Evangelical, non-religious private, and Catholic school students all have lower odds of teenage births than public school students but higher odds of birth later in the life course. Homeschoolers do not differ on either outcome at any age. Our findings suggest that schools socialize their students with distinctive attitudes toward family formation that influence their behavior even many years after graduation, though these schools do not appear to be particularly harmful to life chances in terms of fostering marriage or childbearing at very young ages.     

Evaluation of a Booster Intervention Three Years After Acute Treatment for Early-Onset Disruptive Behavior Disorders

This study examines the impact of a brief booster treatment administered 3 years after the delivery of an acute treatment in a group (n?=?118) of clinically referred boys and girls (ages 6 to 11) originally diagnosed with Oppositional Defiant Disorder (ODD) or Conduct Disorder (CD). At the conclusion of the acute treatment and three-year follow-up period (i.e., study month 42), the sample was re-randomized into Booster treatment or Enhanced Usual Care and then assessed at four later timepoints (i.e., post-booster, and 6-, 12- and 24-month booster follow-up). Booster treatment was directed towards addressing individualized problems and some unique developmental issues of adolescence based on the same original protocol content and treatment setting, whereas the Enhanced Usual Care condition involved providing clinical recommendations based on the assessment and an outside referral for services. HLM analyses identified no significant group differences and few time effects across child, parent, and teacher reports on a broad range of child functioning and impairment outcomes. Analyses examining the role of putative moderators or predictors (e.g., severity of externalizing behavior, dose of treatment) were likewise non-significant. We discuss the nature and implications of these novel findings regarding the role and timing of booster treatment to address the continuity of DBD over time.     

Children Use Temporal Cues to Learn Causal Directionality

The ability to learn the direction of causal relations is critical for understanding and acting in the world. We investigated how children learn causal directionality in situations in which the states of variables are temporally dependent (i.e., autocorrelated). In Experiment 1, children learned about causal direction by comparing the states of one variable before versus after an intervention on another variable. In Experiment 2, children reliably inferred causal directionality merely from observing how two variables change over time; they interpreted Y changing without a change in X as evidence that Y does not influence X. Both of these strategies make sense if one believes the variables to be temporally dependent. We discuss the implications of these results for interpreting previous findings. More broadly, given that many real‐world environments are characterized by temporal dependency, these results suggest strategies that children may use to learn the causal structure of their environments.     

ERNEST BECKER'S PSYCHOLOGY OF RELIGION FORTY YEARS ON: A VIEW FROM SOCIAL COGNITIVE PSYCHOLOGY

This article distinguishes between three projects in Ernest Becker's (1924–1974) later work: his psychology of “religion,” his psychology of religion, and his psychology of Religion (with a capital R). The first is an analysis of culture and civilization as immortality projects, means by which to deny death. The second, which overlaps with the first, is a characterization of religion‐as‐practiced (e.g., by adherents of the world religions) as a particularly effective immortality project vis‐à‐vis death anxiety. The third is less social scientific and more theological; Becker argues for a view of God that is in the tradition of Søren Kierkegaard and Paul Tillich (and, arguably, Pseudo‐Dionysius, Augustine, and Thomas Aquinas). Focusing on the second of these projects—as much has already been written on the first, and little can be said about the third—this article evaluates Becker's claims about religion‐as‐practiced in light of recent developments in social cognitive psychology.     

Frontotemporal neural systems supporting semantic processing in Alzheimer’s disease

We hypothesized that semantic memory for object concepts involves both representations of visual feature knowledge in modality-specific association cortex and heteromodal regions that are important for integrating and organizing this semantic knowledge so that it can be used in a flexible, contextually appropriate manner. We examined this hypothesis in an fMRI study of mild Alzheimer’s disease (AD). Participants were presented with pairs of printed words and asked whether the words matched on a given visual–perceptual feature (e.g., guitar, violin: SHAPE). The stimuli probed natural kinds and manufactured objects, and the judgments involved shape or color. We found activation of bilateral ventral temporal cortex and left dorsolateral prefrontal cortex during semantic judgments, with AD patients showing less activation of these regions than healthy seniors. Moreover, AD patients showed less ventral temporal activation than did healthy seniors for manufactured objects, but not for natural kinds. We also used diffusion-weighted MRI of white matter to examine fractional anisotropy (FA). Patients with AD showed significantly reduced FA in the superior longitudinal fasciculus and inferior frontal-occipital fasciculus, which carry projections linking temporal and frontal regions of this semantic network. Our results are consistent with the hypothesis that semantic memory is supported in part by a large-scale neural network involving modality-specific association cortex, heteromodal association cortex, and projections between these regions. The semantic deficit in AD thus arises from gray matter disease that affects the representation of feature knowledge and processing its content, as well as white matter disease that interrupts the integrated functioning of this large-scale network.
