Prefrontal cortex and the mediation of proactive interference in working memory

Mediating proactive interference (PI), the deleterious effect of antecedent information on current memory representations, is believed to be a key function of prefrontal cortex (PFC). Item-specific PI results when an invalid probe matches a memorandum from the preceding trial; item-nonspecific PI is produced by the accumulation of no-longer-relevant items from previous trials. We tested the hypothesis that these two types of PI are mediated by common PFC-based processes with an fMRI study of a delayed-recognition task designed to produce both types of PI. Our results indicated that the fMRI correlates of both effects were restricted both to Brodmann’s area 45 in the left hemisphere and to the memory probe epoch of the trial. These results suggest that a unification of the literatures and approaches that have independently studied these phenomena might offer a fruitful new perspective from which to study the relations between working memory, executive control, and the PFC.     

More on the fragility of performance: choking under pressure in mathematical problem solving

In 3 experiments, the authors examined mathematical problem solving performance under pressure. In Experiment 1, pressure harmed performance on only unpracticed problems with heavy working memory demands. In Experiment 2, such high-demand problems were practiced until their answers were directly retrieved from memory. This eliminated choking under pressure. Experiment 3 dissociated practice on particular problems from practice on the solution algorithm by imposing a high-pressure test on problems practiced 1, 2, or 50 times each. Infrequently practiced high-demand problems were still performed poorly under pressure, whereas problems practiced 50 times each were not. These findings support distraction theories of choking in math, which contrasts with considerable evidence for explicit monitoring theories of choking in sensorimotor skills. This contrast suggests a skill taxonomy based on real-time control structures.     

Everyday Marital Conflict and Child Aggression

Children's immediate aggressive responding to exposure to marital conflict was examined. Participants were 108 families with 8- to 16-year-old children (53 boys, 55 girls), with diary records of children's reactions to marital conflict in the home completed by 103 mothers (n = 578 records) and 95 fathers (n = 377 records) during a 15-day period. Child responses to analog presentations of marital conflict tactics were also obtained. Exposure to destructive conflict tactics and negative parental emotionality increased the likelihood of aggressive behavior in children when they witnessed marital conflict, whereas constructive conflict tactics and positive parental emotionality decreased the probability of aggression. Conflict topics presumed to be threatening to the child (child- or marital-related) also heightened the likelihood of aggression. Aggressive responding to conflict in both home and laboratory predicted externalizing behavior problems. Fathers' and mothers' separate diary reports, and child responses to analog presentation of conflict, provided generally consistent findings. An exposure hypothesis for marital conflict as an influence on child aggression is discussed.     

Generative Concern, Political Commitment, and Charitable Actions

The implications of psychosocial generativity (Erikson, 1950) for understanding contemporary politics were explored. Study 1 replicated, in two samples, previous findings that generativity concerns are related to a variety of political activities, including the expenditure of time and money in support of political organizations. Using path analyses, Study 2 extended these findings and demonstrated how midlife generativity concerns interacted with political orientation and interest in politics to produce stronger relationships with giving. These findings suggest that people view the political arena as one important way to improve society and thereby manifest cultural generativity. Although focusing on the domain of politics, these studies highlight the complexity of generativity as a construct; broad concerns with generativity operate within the context of ideological commitments to produce greater levels of generative activity.     

The generality of the levels of processing hypothesis: An application to memory for chess positions

The generality of the levels of processing approach to memory was tested by using chess positions rather than words as stimuli. Experiment 1 compared recall following semantic orienting instructions (find the best move and determine which side has the advantage), formal orienting instructions (determine the number of pieces on light squares and the number of pieces on dark squares), and intentional learning instructions using 19 novice chess players as subjects. Formal orienting instructions produced poorer recall than did either semantic orienting or intentional learning instructions, which yielded similar levels of retention. These results were replicated in Experiment 2 with 16 tournament chess players. Chess rating correlated with recall .82 under semantic orienting instructions but only —.15 under formal orienting instructions. It was concluded that the levels of processing framework has applicability outside the area of verbal learning.     

Instrumental to Pavlovian transfer: Learning about response-reinforcer contingencies affects subsequent learning about stimulus-reinforcer contingencies

Two experiments examined the interaction between response-reinforcer (R-S) and stimulus-reinforcer (S-S) learning. In both experiments, three groups of rats were exposed to escapable, yoked inescapable, or no shocks. All groups were then exposed to either two or four sessions of truly random control (TRC) conditioning (Experiment 1) or to an excitatory conditioning procedure (Experiment 2) in which the shock US occurred with either moderate or low probability. Excitatory strength of the CS was assessed during extinction by a conditioned emotional response (CER) test. Inescapably shocked rats conditioned less than did their escapably shocked and nonshocked partners under all TRC conditions of Experiment 1, but only conditioned less than their partners in Experiment 2 when exposed to the moderate CS-US contingency for four sessions. These results provide a clear demonstration of transfer between instrumental training and Pavlovian excitatory conditioning and thus, support the influence of learning about R-S contingencies upon subsequent learning about S-S contingencies. Both a contextual blocking interpretation and an expansion of the learned helplessness theory were discussed as possible explanations of this transfer.     

Are families supported to come to terms with an autism diagnosis? A service evaluation of referrals to family therapy for young people with autism in one NHS trust

Young people with autism are increasingly being referred for family therapy (FT) owing to impaired family functioning, but few studies have investigated the support families receive following a diagnosis through specific NHS Trusts. This study examined (1) the proportion of autism cases referred for FT in one Trust and (2) the post-diagnostic support families received. Participants (n = 144; 9.5–19.3 years) were FT referrals between 2019–2020. Autism diagnostic status and the support families received from FT, from the neurodevelopmental (ND) service which specialises in autism, and for co-occurring conditions [e.g., cognitive behavioural therapy (CBT)] was extracted retrospectively from routine data. Forty FT referrals met autism criteria: several families did not receive FT; few were provided with support from the ND service; and if CBT was offered, no adaptations for autism were noted. Families received insufficient support following a diagnosis through this Trust. Implications include improving post-diagnostic support for families in practice.     

Infant placement and language exposure in daily life

Children's daily contexts shape their experiences. In this study, we assessed whether variations in infant placement (e.g., held, bouncy seat) are associated with infants' exposure to adult speech. Using repeated survey sampling of mothers and continuous audio recordings, we tested whether the use of independence-supporting placements was associated with adult speech exposure in a Southeastern U.S. sample of 60 4- to 6-month-old infants (38% male, predominately White, not Hispanic/Latinx, from higher socioeconomic status households). Within-subject analyses indicated that independence-supporting placements were associated with exposure to fewer adult words in the moment. Between-subjects analyses indicated that infants more frequently reported to be in independence-supporting placements that also provided posture support (i.e., an exersaucer) were exposed to relatively fewer adult words and less consistent adult speech across the day. These findings indicate that infants' opportunities for exposure to adult speech ‘in the wild’ may vary based on immediate physical context.     

Use them or lose them: Are manipulatives needed to assess numeracy and geometry performance in preschool?

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. On a measure of children's shape identification (n = 93), there was no difference in performance between objects and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. These results suggest flexibility in the materials that can be used during assessment. Pictures, or 2D renderings of 3D objects, which can be easily printed and reproduced, may be sufficient for assessing counting and shape knowledge without the need for more cumbersome concrete manipulatives.     

Relationship of Connected and Separate Knowing to Parental Style and Birth Order

A total of 249 primarily middle-class, Caucasian college students (141 females, 108 males) completed the Knowing Styles Inventory (KSI) (Knight, Elfenbein, & Messina, 1995) to measure Connected and Separate Knowing and the Parental Authority Questionnaire (PAQ) (Buri, 1991), used to measure different parenting styles (authoritarian, authoritative, and permissive parenting). Authoritative parenting style of the mother was positively associated with Connected Knowing, while authoritative parenting style of the father was negatively related to Separate Knowing for both the female and male participants of the study. For the female participants only, permissive parenting style of the father was positively related to Separate Knowing. It was also found that first-born college students scored significantly higher on Separate Knowing than later-born students. The results suggest that family experiences may be precursors to the epistemologies of college students.
