AbstractThe main function of pain is to automatically draw attention towards sources of potential injury. However, pain sometimes needs to be inhibited in order to address or pursue more relevant tasks. Elucidating the factors that influence how people manage this relationship between pain and task performance is essential to understanding the disruptive nature of pain and its variability between individuals. Here, 41 healthy adults completed a challenging working memory task (2-back task) while receiving painful thermal stimulations. Examining the trial-by-trial relationship between pain perception and task performance revealed that pain’s disruptive effects on performance were mediated by self-reported pain intensity, and that the analgesic effects of a competing task were influenced by task performance. We found that higher pain catastrophizing, higher trait anxiety, and lower trait mindfulness were associated with larger trade-offs between pain perception and task performance, suggesting that these psychological factors can predict increased fluctuations between disruption by pain and analgesia from a competing task. Altogether these findings provide an important and novel perspective on our understanding of individual differences in the interplay between pain and ongoing task performance.

Cognitive task performance is a dynamic process that evolves over time, starting from the first encounters with a task. An important aspect of these task dynamics is the employment of strategies to support successful performance and task acquisition. Focusing on episodic memory performance, we: (1) tested two hypotheses on the effects of novelty and task difficulty on strategy use; (2) replicated our previous results regarding strategy use in a novel memory task; and (3) evaluated whether repeated open-ended strategy queries affect task performance and/or strategy use. The present pre-registered online study comprised 161 adult participants who were recruited through the Prolific crowdsourcing platform. We employed two separate 5-block list learning tasks, one with 10 pseudowords and the other with 18 common nouns, and collected recall performance and strategy reports for each block. Using Bayesian linear mixed effects models, the present findings (1) provide some support for the hypothesis that task-initial strategy development is not triggered only by task novelty, but can appear also in a familiar, moderately demanding task; (2) replicate earlier findings from an adaptive working memory task indicating strategy use from the beginning of a task, associations between strategy use and objective task performance, and only modest agreement between open-ended vs. list-based strategy reports; and (3) indicate that repeated open-ended strategy reports do not affect objective recall. We conclude that strategy use is an important aspect of memory performance right from the start of a task, and it undergoes development at the initial stages depending on task characteristics. In a larger perspective, the present results concur with the views of skill learning and adaptivity in cognitive task performance.

The dearth of empirical research in the application of biofeedback is discussed. Exp. 1 assessed relationships among biofeedback EMG training, EMG levels, cognitive task performance, and task difficulty. 72 subjects (male or female college students) were administered 1 trial on an iconic memory task with either EMG audio feedback, sham EMG audio feedback, or no feedback. Three levels of task difficulty were used. One 20-min. training session significantly lowered EMG responses, and task performance was inversely related to task difficulty. No relationship between EMG level and task performance was observed. Exp. 2 investigated the effect of increased EMG responses on cognitive task performance for one level of difficulty. One biofeedback training session did not significantly increase frontalis EMG, and there was no relationship between increased EMG and task performance.

Light exerts a number of non-image-forming effects that are mostly apparent during night-time but can also been seen during daytime. Recently, we have shown that exposure to light of higher colour temperature prior to performing a cognitive task leads to a weaker effort-related cardiovascular response compared to exposure to light of lower colour temperature. This present study tested if presenting light of different colour temperatures during rather than before the task performance would lead to equivalent changes in effort mobilization. Participants performed a modified Sternberg short-memory task for eight minutes as lighting conditions were adjusted to one of four experimental lighting conditions (2800 K, 4000 K, 5000 K, or 6500 K) after the first four minutes, for the remaining four minutes. We predicted that effort-related cardiovascular response would strengthen with decreasing colour temperature. The results, however, did not follow this predicted pattern. No significant effects of lighting conditions on subjective measures were observed. Therefore, we conclude that four minutes might not be enough for light colour temperature to induce changes in effort-related cardiovascular response or affect subjective ratings of sleepiness and lighting.

Assessments of self-esteem, IQ, and performance on a cognitively demanding task were obtained from 45 college undergraduates. In addition, subjects were asked to predict how well they thought they would do on the “cognitive task” after having seen one sample problem, to estimate how well they thought they had done after completing all of the problems, how difficult they thought each problem was, and how certain they were that their answer was correct. Analysis indicated that self-esteem was significantly related to performance, independently of the covarying effect of intelligence. Contrary to expectations, however, individuals high in self-esteem did not predict that they would do better, and they did not express more confidence in their answers to the problems. Methodological and substantive implications pertaining to the mechanism whereby self-esteem influences achievement are discussed.

AbstractMentally demanding tasks feel effortful and are usually avoided. Furthermore, prolonged cognitive engagement leads to mental fatigue, consisting of subjective feeling of exhaustion and decline in performance. Despite the intuitive characterization of fatigue as an increase in subjective effort perception, the effect of fatigue on effort cost has never been tested experimentally. To this end, sixty participants in 2 separate experiments underwent a forced-choice working memory task following either a fatigue-inducing (i.e. Stroop task) or a control manipulation. We measured subjective fatigue and effort as well as their objective behavioral signatures: performance decline and task avoidance, respectively. We found that fatigue-induced performance decline was correlated with task avoidance, while the feelings of fatigue and effort were unrelated to each other. Our findings highlight the discrepancy between subjective and objective manifestations of fatigue and effort, and provide valuable evidence feeding the ongoing theoretical debate on the nature of these constructs.

Purpose – This paper aims to assert that teams are a technology used to achieve task goals or social objectives that cannot be accomplished by individuals alone. Much current work in organizations is knowledge based, so it is important to know when to apply teams as a technology and how teams can be effectively utilized for cognitive task performance. This paper describes a number of strengths, weaknesses and trade-offs that accompany teams performing cognitive tasks. Design/methodology/approach – Research comparing team performance to that of similarly treated individuals indicates that teams on average exceed the performance of individuals on cognitive tasks; however, teams rarely match the performance of their best member. Findings – Based on analysis of this research, a set of strengths of teams are highlighted: information pooling, error correction, meta-knowledge, reliability and information sharing. Two weaknesses of team performance on cognitive tasks are also identified: slow to action and coordination losses. As a function of teams having these strengths and weaknesses, trade-offs in their task performance emerge: speed versus accuracy, convergence versus divergence, participation versus deindividuation, losses versus gains in motivation, social facilitation versus inhibition, accumulation versus coordination, focused versus distributed attention and accentuation versus attenuation of biases. Originality/value – These trade-offs demonstrate that teams operate in specific ways that sometimes benefit cognitive processing but will be hindered under other conditions. An understanding of those conditions is important when attempting to effectively use teams. So, “technical” knowledge rather than intuition is required to manage these processes appropriately and effectively.

Purpose – The purpose of this paper is to more thoroughly investigate the role of organizational citizenship behaviors (OCBs) in sales force settings and the reason why salespeople should practice OCBs. In fact, in spite of the huge body of literature on OCBs and their impact on performance, some important knowledge gaps still remain to be filled. Inconsistent and unexpected findings are particularly apparent in the relatively few studies investigating OCBs in sales forces. The authors argue that some specific characteristics of the selling job and related tasks make the analysis of the practice of these behaviors in the sales context particularly interesting. Design/methodology/approach – The authors explore which OCBs salespeople engage in, and analyze the perceived consequences of such behaviors using means-end theory and the laddering technique. They apply means-end theory and the laddering technique to interview a sample of salespersons from three companies operating in different business-to-business settings. Findings – The end result of the empirical analysis is the hierarchical value map showing a set of linkages among OCBs and their perceived consequences. In the perceptions of salespeople, OCBs play a strong utilitarian role in that they facilitate personal goal attainment. In salespeople’s minds, there are no relevant trade-offs between OCBs and task-performance as long as the former can be used to improve the latter. For salespeople, the path from OCBs to performance may vary, depending on whether the performance in question is organizational, individual or customer-focused. Finally, some OCBs apparently contribute to creating customer trust in the salesperson. Research limitations/implications – The findings add some interesting insights to the discussion regarding some controversies in OCBs literature, especially the interplay of contextual performance and task performance. Practical implications – Various types of OCBs can be encouraged through different managerial interventions. As an example, altruism can be fostered by appropriate recruiting criteria (e.g. using “attitude toward teamwork” as a key personnel selection factor), and by training initiatives and leadership style. Altruism can also be stimulated by an adequately designed organizational structure (e.g. team-based) as well as by adopting appropriate integration mechanisms that facilitate interpersonal and interfunctional cooperation. Sales managers can foster some OCBs by promoting knowledge sharing and reciprocal learning among members of the sales team, and by emphasizing the positive consequences of OCBs in all communication with salespeople. Originality/value – Findings from this study challenge some widespread assumptions about OCBs in general. In fact, most of the literature holds that OCBs are an example of prosocial behaviors. Actually, the findings suggest that in the specific case of salespeople, OCBs are ultimately self-directed, for the most part.

Theory and some empirical research suggest that there is a relationship between emotions and performance on cognitive tasks. The construct of emotional intelligence may provide a vehicle for exploring the connection between emotions and cognitive task performance. The present study tested the hypotheses that: a) individuals with higher emotional intelligence would perform better on cognitive tasks; and b) they would be better able to deal with the frustration or helplessness that may result from encountering very difficult tasks. Participants recruited from community and university settings participated in a study in which their emotional intelligence was assessed and they worked on three sets of anagrams. The first set of anagrams was moderately difficult, the second set was very difficult, and the third set was again moderately difficult. The first hypothesis was supported in that participants higher in emotional intelligence solved more problems on the first set of moderately difficult anagrams. The second hypothesis was supported in that the participants higher in emotional intelligence solved more problems after encountering a very difficult and frustrating set of problems, even when initial performance was held constant. The results suggest that study of the emotional intelligence construct holds promise for better understanding and perhaps in the future enhancing cognitive task performance.
