Disequilibrium in the mind,disharmony in the body

Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or “fractal scaling”, during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.     

Eye movements and problem solving: guiding attention guides thought

Overt visual attention during diagram-based problem solving, as measured by eye movements, has been used in numerous studies to reveal critical aspects of the problem-solving process that traditional measures like solution time and accuracy cannot address. In Experiment 1, we used this methodology to show that particular fixation patterns correlate with success in solving the tumor-and-lasers radiation problem. Given this correlation between attention to a particular diagram feature and problem-solving insight, we investigated participants' cognitive sensitivity to perceptual changes in that diagram feature. In Experiment 2, we found that perceptually highlighting the critical diagram component, identified in Experiment 1, significantly increased the frequency of correct solutions. Taking a situated perspective on cognition, we suggest that environmentally controlled perceptual properties can guide attention and eye movements in ways that assist in developing problem-solving insights that dramatically improve reasoning.     

The social foundation of executive function

In this study, we propose that infant social cognition may ‘bootstrap' the successive development of domain‐general cognition in line with the cultural intelligence hypothesis. Using a longitudinal design, 6‐month‐old infants (N = 118) were assessed on two basic social cognitive tasks targeting the abilities to share attention with others and understanding other peoples' actions. At 10 months, we measured the quality of the child's social learning environment, indexed by parent's abilities to provide scaffolding behaviors during a problem‐solving task. Eight months later, the children were followed up with a cognitive test‐battery, including tasks of inhibitory control and working memory. Our results showed that better infant social action understanding interacted with better parental scaffolding skills in predicting simple inhibitory control in toddlerhood. This suggests that infants' who are better at understanding other's actions are also better equipped to make the most of existing social learning opportunities, which in turn may benefit future non‐social cognitive outcomes.     

Age-related effects of blood pressure on everyday cognitive function in community-dwelling women

ABSTRACT

Objectives: Blood pressure is an indicator of vascular health that has been associated with cognition and quality of life in older age. Few studies have examined blood pressure across everyday cognitive tasks, which may have superior predictive functional utility than traditional cognitive measures. We explored blood pressure as a predictor of everyday problem solving (EPS) performance in middle-aged and older women. Method: Community-dwelling women (age: 51–91) with low-normal blood pressure to mild hypertension underwent traditional and everyday cognitive testing. EPS was determined by the number of safe/effective solutions generated for real-world scenarios. Results: Analyses revealed that lower systolic blood pressure and pulse pressure were associated with worse EPS ability after controlling for age, education, and traditional cognitive abilities. Discussion: These results support that blood pressure may be an important predictor of everyday cognitive abilities in older age. Potential implications for real-world functioning are discussed.     

Assessing learning and memory in pigs

In recent years, there has been a surge of interest in (mini) pigs (Sus scrofa) as species for cognitive research. A major reason for this is their physiological and anatomical similarity with humans. For example, pigs possess a well-developed, large brain. Assessment of the learning and memory functions of pigs is not only relevant to human research but also to animal welfare, given the nature of current farming practices and the demands they make on animal health and behavior. In this article, we review studies of pig cognition, focusing on the underlying processes and mechanisms, with a view to identifying. Our goal is to aid the selection of appropriate cognitive tasks for research into pig cognition. To this end, we formulated several basic criteria for pig cognition tests and then applied these criteria and knowledge about pig-specific sensorimotor abilities and behavior to evaluate the merits, drawbacks, and limitations of the different types of tests used to date. While behavioral studies using (mini) pigs have shown that this species can perform learning and memory tasks, and much has been learned about pig cognition, results have not been replicated or proven replicable because of the lack of validated, translational behavioral paradigms that are specially suited to tap specific aspects of pig cognition. We identified several promising types of tasks for use in studies of pig cognition, such as versatile spatial free-choice type tasks that allow the simultaneous measurement of several behavioral domains. The use of appropriate tasks will facilitate the collection of reliable and valid data on pig cognition.     

When Reflection Hinders Creative Problem-Solving: a Test of Alternative Reflection Strategies

A growing body of evidence suggests that reflecting on performance is an important source of individual learning. Given the importance of creativity in contemporary business settings, reflection has also been cast as a useful strategy to facilitate creative problem-solving. Challenging this idea, we conducted a series of lab experiments to examine the effects of reflection on creative problem-solving. Drawing from theory in cognitive psychology on knowledge structures, we argue that reflection may sometimes debilitate rather than improve creative problem-solving, due to the reinforcement of existing cognitive schemas and the resulting cognitive entrenchment. To test our theoretical arguments, we developed two alternative reflection strategies, imaginative reflection and vicarious elaboration. In Study 1 (N = 101), we observed a detrimental effect of task reflection on creative problem-solving, which was offset by having participants engage in imaginative reflection. In Study 2 (N = 191), vicarious elaboration, elaborating on another’s creative experiences instead of reflecting on one’s own creative experiences, was introduced as a second strategy to counter cognitive entrenchment. In Study 3 (N = 235), we combined the reflection strategies, demonstrating that imaginative thinking was more effective when focused on one’s own experiences rather than on others’ experiences (i.e., vicarious imaginative elaboration). Together, these findings increase our understanding of the effects of different reflection strategies, but also call for further research to address an intriguing observation: none of the reflection strategies led to better outcomes as compared to a control condition without reflection, suggesting that individual reflection might not help creative problem-solving at all.

     

Compliance and Problem-Solving Competence in Girls and Boys

The problem-solving abilities of 4- and 5-year old children (N = 208) were assessed to test the hypothesis that high levels of compliance are negatively related to problem solving. Problem-solving competence was examined with a task-specific measure and a standardized measure of general problem-solving performance. Low compliant children performed better on both measures. The role of compliance in the cognitive development of girls and boys is discussed.     

Expecting tasks to help or hurt subsequent cognitive performance: Variability,accuracy, and bias in forecasted after-effects

After-effects on cognition—where a prior activity either benefits or hinders subsequent cognitive performance—are empirically inconsistent. Do people have insight into when their subjective energy and cognition will be helped or hurt by engaging in prior activities? Studies 1a and 1b (combined N  =  316) find that people expect more demanding and unenjoyable tasks to hinder their subsequent energy and cognitive performance, regardless of their willpower lay theory. Study 2 (N  =  167) examines the accuracy of these forecasts using a within-subject design. Participants’ forecasts of their future subjective states did predict their actual experienced subjective states, but participants were not able to accurately forecast their subsequent maths performance. Additionally, they significantly overestimated the detrimental effects of demanding prior activities on both subjective state and performance. Study 3 (N  =  210) found that participants’ overestimation of detrimental after-effects could result in unnecessary financial costs, suggesting these biased forecasts can have consequences.     

Influence of personality,age, sex,and estrous state on chimpanzee problem-solving success

Despite the importance of individual problem solvers for group- and individual-level fitness, the correlates of individual problem-solving success are still an open topic of investigation. In addition to demographic factors, such as age or sex, certain personality dimensions have also been revealed as reliable correlates of problem-solving by animals. Such correlates, however, have been little-studied in chimpanzees. To empirically test the influence of age, sex, estrous state, and different personality factors on chimpanzee problem-solving, we individually tested 36 captive chimpanzees with two novel foraging puzzles. We included both female (N = 24) and male (N = 12) adult chimpanzees (aged 14–47 years) in our sample. We also controlled for the females’ estrous state—a potential influence on cognitive reasoning—by testing cycling females both when their sexual swelling was maximally tumescent (associated with the luteinizing hormone surge of a female’s estrous cycle) and again when it was detumescent. Although we found no correlation between the chimpanzees’ success with either puzzle and their age or sex, the chimpanzees’ personality ratings did correlate with responses to the novel foraging puzzles. Specifically, male chimpanzees that were rated highly on the factors Methodical, Openness (to experience), and Dominance spent longer interacting with the puzzles. There was also a positive relationship between the latency of females to begin interacting with the two tasks and their rating on the factor Reactivity/Undependability. No other significant correlations were found, but we report tentative evidence for increased problem-solving success by the females when they had detumescent estrous swellings.     

Experience and Distribution of Attention: Pet Exposure and Infants’ Scanning of Animal Images

Although infants’ cognitions about the world must be influenced by experience, little research has directly assessed the relation between everyday experience and infants’ visual cognition in the laboratory. Eye-tracking procedures were used to measure 4-month-old infants’ eye movements as they visually investigated a series of images. Infants with pet experience (N = 27) directed a greater proportion of their looking at the most informative region of animal stimuli—the head—compared with infants without such experience (N = 21); the two groups of infants did not differ in their scanning of images of human faces or vehicles. Thus, infants’ visual cognitions are influenced by everyday experience, and theories of cognitive development in infancy must account for the effect of experience on development.     

Assessing complex problem-solving skills with multiple complex systems

In this paper we propose the multiple complex systems (MCS) approach for assessing domain-general complex problem-solving (CPS) skills and its processes knowledge acquisition and knowledge application. After defining the construct and the formal frameworks for describing complex problems, we emphasise some of the measurement issues inherent in assessing CPS skills with single tasks (i.e., fixed item difficulty, low or unknown reliability, and a large impact of random errors). With examples of the MicroDYN test and the MicroFIN test (two instances of the MCS approach), we show how to adequately score problem-solving skills by using multiple tasks. We discuss implications for problem-solving research and the assessment of CPS skills in general.     

Lions (<Emphasis Type="Italic">Panthera leo</Emphasis>) solve,learn, and remember a novel resource acquisition problem

The social intelligence hypothesis proposes that the challenges of complex social life bolster the evolution of intelligence, and accordingly, advanced cognition has convergently evolved in several social lineages. Lions (Panthera leo) offer an ideal model system for cognitive research in a highly social species with an egalitarian social structure. We investigated cognition in lions using a novel resource task: the suspended puzzle box. The task required lions (n = 12) to solve a novel problem, learn the techniques used to solve the problem, and remember techniques for use in future trials. The majority of lions demonstrated novel problem-solving and learning; lions (11/12) solved the task, repeated success in multiple trials, and significantly reduced the latency to success across trials. Lions also demonstrated cognitive abilities associated with memory and solved the task after up to a 7-month testing interval. We also observed limited evidence for social facilitation of the task solution. Four of five initially unsuccessful lions achieved success after being partnered with a successful lion. Overall, our results support the presence of cognition associated with novel problem-solving, learning, and memory in lions. To date, our study is only the second experimental investigation of cognition in lions and further supports expanding cognitive research to lions.     

Effects of Solution Elicitation Aids and Need for Cognition on the Generation of Solutions to Ill-Structured Problems

Numerous techniques have been proposed to assist problem solvers in the solution generation process. We empirically examined the effectiveness of a solution elicitation technique based on the presentation of problem objectives and also examined whether the technique was effective across individual differences in need for cognition (NC). We found that when two conflicting objectives were presented successively, more solutions, more categories of solutions, and more effective solutions were generated than when the same two objectives were presented simultaneously or not at all. However, the results indicated that effective solutions may be more efficiently generated by considering objectives simultaneously. Need for cognition was positively related to measures of divergent thinking, and the presentation of objectives was particularly effective as a solution elicitation aid for individuals with low NC. Implications for creative problem-solving research and practice are discussed.     

The effect of Multi Convergent Therapy on the psychopathology,mood and performance of Chronic Fatigue Syndrome patients: A preliminary study

Objectives: Multi Convergent Therapy combines approaches such as Cognitive Behaviour Therapy and Graded Exercise Therapy in an holistic treatment of Chronic Fatigue Syndrome. Initial follow‐up data showed that patients were benefiting from this individualised form of therapy. The objective of the present study was to evaluate this Multi Convergent approach, developed at a specialised Chronic Fatigue Syndrome Outpatient clinic in Cardiff, and compare it to Relaxation Therapy and control groups using multiple outcome measures. Design: Thirty‐five participants fitting the Centre for Disease Control criteria for Chronic Fatigue Syndrome were recruited from two outpatient clinics and members of our existing patient panel. Patients were assigned to Multi Convergent Therapy (N=12), Relaxation Therapy (N=14) or recruited as controls (N=9). Methods: Each patient completed a battery of mood and performance tasks along with comprehensive set of questionnaires at baseline, post‐treatment and at six‐month follow‐up. These measures had been validated in previous studies on untreated patients and matched healthy controls. Results: Patients attending the Multi Convergent Therapy clinic showed statistically significant improvements in many of our measures. Most importantly we have produced data indicating that Multi Convergent Therapy provides improvements in objective measures of psychomotor performance and cognition. Discussion: The outcomes of this small study are encouraging. Multi Convergent Therapy has not only produced results indicating significant improvements in standardised questionnaire based measures but also in objective cognitive performance tasks. The next step would be to assess Multi Convergent Therapy at the primary medical care level, with a greater number of patients to further evaluate its efficacy as a treatment for Chronic Fatigue Syndrome.     

Can false memories prime alternative solutions to ambiguous problems?

Research has demonstrated that false memories are capable of priming and facilitating insight-based problem-solving tasks by increasing solution rates and decreasing solution times. The present research extended this finding by investigating whether false memories could be used to bias ambiguous insight-based problem-solving tasks in a similar manner. Compound remote associate task (CRAT) problems with two possible correct answers, a dominant and a non-dominant solution, were created and normed (Experiment 1). In Experiment 2, participants were asked to solve these CRAT problems after they were given Deese/Roediger-McDermott lists whose critical lures were also the non-dominant solution to half of the corresponding CRATs. As predicted, when false memories served as primes, solution rates were higher and solution times were faster for non-dominant than dominant CRAT solutions. This biasing effect was only found when participants falsely recalled the critical lure, and was not found when participants did not falsely recall the critical lure, or when they were not primed. Results are discussed with regard to spreading activation models of solution competition in problem-solving tasks and current theories of false memory priming effects.     

Swinging into thought: Directed movement guides insight in problem solving

Can directed actions unconsciously influence higher order cognitive processing? We investigated how movement interventions affected participants’ ability to solve a classic insight problem. The participants attempted to solve Maier’s two-string problem while occasionally taking exercise breaks during which they moved their arms either in a manner related to the problem’s solution (swing group) or in a manner inconsistent with the solution (stretch group). Although most of the participants were unaware of the relationship between their arm movement exercises and the problem-solving task, the participants who moved their arms in a manner that suggested the problem’s solution were more likely to solve the problem than were those who moved their arms in other ways. Consistent with embodied theories of cognition, these findings show that actions influence thought and, furthermore, that we can implicitly guide people toward insight by directing their actions.     

Different faces of (un)controllability: Control restoration modulates the efficiency of task switching

Uncontrollability has been often associated with impaired or rigid cognitive processing. However, perceived stability of uncontrollable events modulated some of these detrimental effects on cognition. We investigated whether the experience of sequential control loss and restoration can enhance cognitive flexibility. We manipulated uncontrollability using a concept formation procedure that entailed either only unsolvable tasks (control deprivation condition), unsolvable tasks followed by solvable ones (control restoration condition) or only solvable tasks (control condition). To assess cognitive flexibility, we used a task-switching procedure that incorporated social categories. In Experiment 1 participants categorized people based on gender or age, and in Experiment 2 and 3 based on gender or social roles. Participants showed more flexibility in control restoration than in control deprivation condition. Additionally, in Experiments 2 and 3 this effect was mainly pronounced in the condition where the task evoked more cognitive conflict. We discuss the motivational underpinnings of unstable experiences of control loss and restoration.

     

Mistakes on display: Incorrect examples refine equation solving and algebraic feature knowledge

Although findings from cognitive science have suggested learning benefits of confronting errors (Metcalfe, 2017), they are not often capitalized on in many mathematics classrooms (Tulis, 2013). The current study assessed the effects of examples focused on either common mathematical misconceptions and errors or correct concepts and procedures on algebraic feature knowledge and solving quadratic equations. Middle school algebra students (N = 206) were randomly assigned to four conditions. Two errorful conditions either displayed errors and asked students to explain or displayed correct solutions and primed students to reflect on potential errors by problem type. A correct example condition and problem-solving control group were also included. Studying and explaining common errors displayed in incorrect examples improved equation-solving ability. An aptitude-by-treatment interaction revealed that learners with limited understandings of algebraic features demonstrated greater benefits. Theoretical implications about using examples to promote learning from errors are considered in addition to suggestions for educational practice.     

Practice makes perfect: familiarity of task determines success in solvable tasks for free-ranging dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

Domestic dogs’ (Canis lupus familiaris) socio-cognitive faculties have made them highly sensitive to human social cues. While dogs often excel at understanding human communicative gestures, they perform comparatively poorly in problem-solving and physical reasoning tasks. This difference in their behaviour could be due to the lifestyle and intense socialization, where problem solving and physical cognition are less important than social cognition. Free-ranging dogs live in human-dominated environments, not under human supervision and are less socialized. Being scavengers, they often encounter challenges where problem solving is required in order to get access to food. We tested Indian street dogs in familiar and unfamiliar independent solvable tasks and quantified their persistence and dependence on a novel human experimenter, in addition to their success in solving a task. Our results indicate that free-ranging dogs succeeded and persisted more in the familiar task as compared to the unfamiliar one. They showed negligible amount of human dependence in the familiar task, but showed prolonged gazing and considerable begging behaviour to the human experimenter in the context of the unfamiliar task. Cognitive abilities of free-ranging dogs thus play a pivotal role in determining task-associated behaviours based on familiarity. In addition to that, these dogs inherently tend to socialize with and depend on humans, even if they are strangers. Our results also illustrate free-ranging dogs’ low competence at physical cognitive tasks.     

The development of creative cognition across adolescence: distinct trajectories for insight and divergent thinking

We examined developmental trajectories of creative cognition across adolescence. Participants (N = 98), divided into four age groups (12/13 yrs, 15/16 yrs, 18/19 yrs, and 25–30 yrs), were subjected to a battery of tasks gauging creative insight (visual; verbal) and divergent thinking (verbal; visuo‐spatial). The two older age groups outperformed the two younger age groups on insight tasks. The 25–30‐year‐olds outperformed the two youngest age groups on the originality measure of verbal divergent thinking. No age‐group differences were observed for verbal divergent thinking fluency and flexibility. On divergent thinking in the visuo‐spatial domain, however, only 15/16‐year‐olds outperformed 12/13‐year‐olds; a model with peak performance for 15/16‐years‐old showed the best fit. The results for the different creativity processes are discussed in relation to cognitive and related neurobiological models. We conclude that mid‐adolescence is a period of not only immaturities but also of creative potentials in the visuo‐spatial domain, possibly related to developing control functions and explorative behavior.
