Reconfiguration of task-set: Is it easier to switch to the weaker task?

Switching between two tasks afforded by the same stimuli results in slower reactions and more errors on the first stimulus after the task changes. This “switch cost” is reduced, but not usually eliminated, by the opportunity to prepare for a task switch. While there is agreement that this preparation effect indexes a control process performed before the stimulus, the “residual” cost has been attributed to several sources: to a control process essential for task-set reconfiguration that can be carried out only after the stimulus onset, to probabilistic failure to engage in preparation prior to the stimulus, and to two kinds of priming from previous trials: positive priming of the now-irrelevant task set and inhibition of the now-relevant task-set. The main evidence for the carry-over of inhibition is the observation that it is easier to switch from the stronger to the weaker of a pair of tasks afforded by the stimulus than vice versa. We survey available data on interactions between task switching and three manipulations of relative task strength: pre-experimental experience, stimulus-response compatibility, and intra-experimental practice. We conclude that it is far from universally true that it is easier to switch to the weaker task. Either inhibition of the stronger task-set is a strategy used only in the special case of extreme inequality in strength, or its consequences for later performance may be masked by slower post-stimulus control operations for more complex tasks. Inhibitory priming may also be stimulus specific. Received: 31 March 1999 / Accepted: 23 July 1999     

A 32-society investigation of the influence of perceived economic inequality on social class stereotyping

There is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of wealth-based categorization in explaining this relationship. We found that people who perceived higher economic inequality were indeed more likely to consider wealth as a meaningful basis for categorization. Unexpectedly, however, higher levels of perceived inequality were associated with perceiving the wealthy as less competent and assertive and the poor as more competent and assertive. Unpacking this further, exploratory analyses showed that the observed tendency to stereotype the wealthy negatively only emerged in societies with lower social mobility and democracy and higher corruption. This points to the importance of understanding how socio-structural features that co-occur with economic inequality may shape perceptions of the wealthy and the poor.     

Intense classification training to increase the detection of drowning swimmers

Lifeguards engage in a continuous process of deciding whether swimmers are in danger or not. The variety of behaviours that distressed swimmers show makes it difficult to impart declarative knowledge to this effect during lifeguard training. As an alternative, we propose a novel training tool that requires novice participants to rapidly categorise 3-s video clips of real-life swimmers as either ‘safe’ or ‘drowning’. A control group also completed a sham intervention, with surfers that may ‘fall’. Due to the complex nature of swimming pools, a scaffolded training approach was employed, which gradually increased the amount of background information over subsequent training rounds. Results demonstrated that the drowning classification training improved responses in a subsequent drowning detection test, compared with the active control-group. The scaffolded approach appeared to prepare participants for processing swimmers in the drowning-detection test. The results provide a foundation for a novel training protocol to improve lifeguard skills.     

An evaluation of Headsprout early reading as an online parent-mediated intervention for primary school children

Due to the Coronavirus pandemic and lengthy absences from the classroom, there is a need for large-scale remedial programs to support young children to “catch-up” on literacy and numeracy skills. A stratified randomized controlled trial was used to evaluate the Headsprout Early Reading (HER) program as a parent-mediated digital literacy intervention. A between-groups design compared differences in reading-dependent outcome measures for 36 children assigned to one of three intervention groups: with support, without support, and waitlist-control. Children completed significantly more episodes when parents received implementation support from the researcher compared to the without support group. Children receiving Headsprout instructions demonstrated marginally greater gains than the waitlist-control group in posttest outcome measures; however, differences in reading outcomes were not significant between groups at posttesting. The current research provides tentative support for HER and importantly, highlights the importance of providing support for parents implementing interventions at home.     

Baby steps: investigating the development of perceptual–motor couplings in infancy

There are cells in our motor cortex that fire both when we perform and when we observe similar actions. It has been suggested that these perceptual‐motor couplings in the brain develop through associative learning during correlated sensorimotor experience. Although studies with adult participants have provided support for this hypothesis, there is no direct evidence that associative learning also underlies the initial formation of perceptual–motor couplings in the developing brain. With the present study we addressed this question by manipulating infants’ opportunities to associate the visual and motor representation of a novel action, and by investigating how this influenced their sensorimotor cortex activation when they observed this action performed by others. Pre‐walking 7–9‐month‐old infants performed stepping movements on an infant treadmill while they either observed their own real‐time leg movements (Contingent group) or the previously recorded leg movements of another infant (Non‐contingent control group). Infants in a second control group did not perform any steps and only received visual experience with the stepping actions. Before and after the training period we measured infants’ sensorimotor alpha suppression, as an index of sensorimotor cortex activation, while they watched videos of other infants’ stepping actions. While we did not find greater sensorimotor alpha suppression following training in the Contingent group as a whole, we nevertheless found that the strength of the visuomotor contingency experienced during training predicted the amount of sensorimotor alpha suppression at post‐test in this group. We did not find any effects of motor experience alone. These results suggest that the development of perceptual–motor couplings in the infant brain is likely to be supported by associative learning during correlated visuomotor experience.

Thou Shalt Not Covet Another Man? Exploring Constructions of Same‐Sex and Different‐Sex Infidelity Using Story Completion

This study explores conceptualisations of same‐ versus different‐sex infidelity in the context of a heterosexual marriage using story completion. A convenience sample of 57 female and male participants completed one of four versions of a story stem featuring a husband who is either emotionally or sexually unfaithful with a woman or a man. A social constructionist thematic analysis found that same‐sex infidelity was conceptualised as the ‘worst case scenario’ and was underpinned by a heteronormative framing of repressed homosexuality. By contrast, heterosexual infidelity was understood in terms of relational deficits and the wife assuming responsibility for these. Overall, the analysis shows that in making sense of same‐sex and heterosexual infidelity, the participants drew on familiar discourses of sexuality and gender, suggesting that despite social psychological theorising related to sexual fluidity, essentialist ideas remain firmly in place. Methodologically, the study demonstrates the usefulness of a rarely used tool—the story completion task—for accessing socio‐cultural discourses and dominant meanings surrounding a particular topic.

Decision-making and the framing effect in a foreign and native language

Recent research using scenarios such as the Asian disease problem has demonstrated a “foreign-language effect”, whereby the framing effect (tendency to be risk-averse in a gain frame and risk seeking in a loss frame) is not (or not as) apparent in the foreign language as the native language. The aim of the current study was to further investigate decision-making and the framing effect in a native language, Thai and a foreign language, English, using the Asian disease/Financial crisis problem (Study 1) and a novel financial decision-making task (Study 2). Results from Study 1 confirmed previous findings as a foreign-language effect emerged. In contrast, in Study 2, a framing effect emerged in both the native and foreign languages of the Thai participants. These contradictory results point to language factors as well as emotional and cognitive demands of the task contributing to the occurrence of the foreign-language effect.     

Predicting Behavioral Career Commitment of College Students With Attachment and Separation Relationships

This study compares the behavioral and attitudinal career commitment of college students, then examines the influences of parental attachment and separation on career commitment. Undergraduates (N = 195) from 3 academic programs were surveyed: a combined degree program that accepts students simultaneously into bachelor's and medical programs, premedical curriculum alone, and general university enrollment. Behavioral career commitment (enrollment in one of the aforementioned programs) correlated with attitudinal commitment for the combined degree and general enrollment groups. Greater attachment to father and less separation from parents were associated with lower career commitment for men. Attachment and separation did not predict career commitment for women.
