Working memory (WM) is crucial for reasoning, learning, decision-making and academic achievement. In diverse contexts, how a task is framed pertaining to its demands and consequences can influence participants' task performance by modifying their cognitive appraisals. However, less is known about the effect of task framing on WM performance and the mechanisms. This study examined whether opportunity- and risk-focused task framing would influence university students' WM performance by altering their cognitive appraisals and affective experiences. Ninety-seven university students were randomly assigned to one of the three framing conditions (Opportunity, Risk, vs. Null), and received instructions that differed in consequences (gain for top performers, loss for poor performers, vs. null), goals (approach, avoidance, vs. neutral), and feedback on personal competence (adequate, inadequate, vs. null). Challenge and threat appraisals, affect, and WM performance were measured before and after task framing. Results showed that opportunity-focused task framing improved students' WM performance, whilst risk-focused task framing increased threat appraisal and decreased positive affect, and that challenge appraisal was not altered in any condition. Female students were influenced by task framing to a greater extent than were male students. Mediation analysis revealed that the alteration of threat appraisal and the change in positive affect mediated the effect of task framing on WM performance. Findings highlight the important role of modifying cognitive appraisals and affective responses in optimizing cognitive performance.

Rumination and worry are common forms of perseverative cognitions in children. Research has started to target perseverative cognitions in the everyday life of children, however, valid measurement instruments reliably capturing rumination and worry in children’s daily life are still missing. We conducted two ambulatory assessment studies validating short scales suitable for the measurement of rumination and worry in children’s daily life. Results of the first study (N = 110, 8 – 11-year olds, 31 days, up to 4 daily measurements) supported a unidimensional structure of the rumination scale with high levels of reliability. Rumination was associated with negative affect (but not positive affect) on the within- and on the between-person level. On the between-person level, children who ruminated more showed poorer working memory performance. In the second study (N = 84, 8 – 10-year olds, 21 days, up to 3 daily measurements), findings of Study 1 were largely replicated. Moreover, we established a unidimensional worry scale in Study 2 reliably capturing worry in children’s daily life. Importantly, Study 2 showed that worry and rumination can be differentiated in children. On the within-person level, higher levels of worry were associated with higher levels of negative affect and lower levels of positive affect. On the between-person level, worry was associated with higher levels of negative affect and lower working memory performance. Altogether, findings of both studies demonstrated that the short scales had excellent psychometric properties suggesting that they are helpful tools for the assessment of rumination and worry in children’s daily life.

Working memory (WM) performance can be improved by an informative cue presented during storage. This effect, termed a retro-cue benefit, can be used to explore mechanisms of attentional prioritization in WM. Directing attention to a single item stored in memory is known to increase memory precision while decreasing the likelihood of incorrect item reports and random guesses, but it is unclear whether similar benefits manifest when participants direct attention to multiple items stored in memory. We tested this possibility by quantifying memory performance when participants were cued to prioritize one or two items stored in working memory. Consistent with prior work, cueing participants to prioritize a single memory item yielded higher recall precision, fewer swap errors, and fewer guesses relative to a neutral cue condition. Conversely, cueing participants to prioritize two memory items yielded fewer swap errors relative to a neutral condition, but no differences in recall precision or guess rates. Although swap rates were less likely during the cue-two vs. neutral conditions, planned comparisons revealed that when participants made swap errors during cue-two trials they were far more likely to confuse two prioritized stimuli than they were to confuse a prioritized stimulus vs. a non-prioritized stimulus. Our results suggest that it is possible to prioritize multiple items stored in memory, with the caveat that doing so may increase the probability of confusing prioritized items.
