Spatial construction skills of chimpanzees (Pan troglodytes) and young human children (Homo sapiens sapiens)

Spatial construction tasks are basic tests of visual‐spatial processing. Two studies have assessed spatial construction skills in chimpanzees (Pan troglodytes) and young children (Homo sapiens sapiens) with a block modelling task. Study 1a subjects were three young chimpanzees and five adult chimpanzees. Study 1b subjects were 30 human children belonging to five age groups (24, 30, 36, 42, 48 months). Subjects were given three model constructions to reproduce: Line, Cross‐Stack and Arch, which differed in type and number of spatial relations and dimensions, but required comparable configurational understanding. Subjects’ constructions were rated for accuracy. Our results show that: (1) chimpanzees are relatively advanced in constructing in the vertical dimension; (2) Among chimpanzees only adults make accurate copies of constructions; (3) Chimpanzees do not develop in the direction of constructing in two dimensions as human children do starting from age 30 months. The pattern of development of construction skills in chimpanzees partially diverges from that of human children and indicates that spatial analysis and spatial representation are partially different in the two species.     

Why are idioms recognized fast?

It is an established fact that idiomatic expressions are fast to process. However, the explanation of the phenomenon is controversial. Using a semantic judgment paradigm, where people decide whether a string is meaningful or not, the present experiment tested the predictions deriving from the three main theories of idiom recognition—the lexical representation hypothesis, the idiom decomposition hypothesis, and the configuration hypothesis. Participants were faster at judging decomposable idioms, nondecomposable idioms, and clichés than at judging their matched controls. The effect was comparable for all conventional expressions. The results were interpreted as suggesting that, as posited by the configuration hypothesis, the fact that they are known expressions, rather than idiomaticity, explains their fast recognition.     

A comparison of ultra-endurance cyclists in a qualifying ultra-cycling race for Paris-Brest-Paris and Race Across America-Swiss cycling marathon

Ultra-endurance events test the adaptation of human physiology to extreme physical and mental demands, high levels of training, motivation, and physical conditioning among participants. To understand basic differences among participants according to the severity of the race, participants in qualifying events for two ultra-endurance cycling races, differing in length and intensity, were compared on measures of anthropometry, training, and support. One race was four times longer, required supporting teams, and racers typically had little sleep, which should lead to the qualifiers being substantially more highly trained than those from the shorter race. The qualifiers in the longer race had greater intensity in training while the qualifiers in the shorter race relied more on training volume. Different strategies and types of training reflected the different demands of the races. Future studies should evaluate personality and motivational differences in ultra-endurance events and between these athletes and athletes in other sports.     

Promoting Functional Ambulation with People with Blindness and Multiple Disabilities

An intervention package comprising auditory cues, physical prompts preceded by vibratory (anticipatory) stimuli, and reinforcement was used to promote ambulation to target places with 2 men with total blindness, profound intellectual disability, and behavioural problems. Data showed that both men acquired successful ambulation to the target places, becoming almost totally independent of the physical prompts. Implications of the findings are discussed.     

Relationship of Illness Severity with Health and Life Satisfaction in Patients with Cardiovascular Disease: The Mediating Role of Self-efficacy Beliefs and Illness Perceptions

Guidelines for cardiovascular rehabilitation from different countries underline the importance of psychological factors in the achievement of improved clinical conditions and quality of life in patients with cardiovascular disease (CVD). Nevertheless, little research has been performed to identify the specific factors that greatly affect or foster patients’ quality of life. The aim of the current study was to investigate the contribution of illness perceptions (IP) and self-efficacy beliefs (SE) on the impact exerted by illness severity on health and life satisfaction in patients with CVD undergoing a rehabilitation program. The study had a cross-sectional design and involved 116 patients (mean age = 65.6 years; SD = 10.0 years; 79.3 % men). Illness severity was measured in terms of left ventricular ejection fraction (LVEF) at the discharge from the cardiology department, whereas psychological factors were assessed one week later. The results showed no relationships among LVEF and the two indicators of health and life satisfaction; moreover, these two variables are differently influenced by IP and cardiac risk factors SE (χ²(1) = 0.96, p = n.s.). Findings provide important suggestions for the implementation of interventions aimed at bettering patients’ quality of life, underlying the importance of working on IP and SE to improve levels of health and life satisfaction in patients with CVD.     

Drawing perseveration in neglect: Effects of target density

In cancellation tasks, patients with unilateral spatial neglect typically fail to mark targets within the side of the sheet contralateral to the side of the lesion (contralesional). Moreover, they can show a perseverative behaviour, which consists in repeatedly cancelling stimuli, mainly in the side of the display ipsilateral to the side of the lesion (ipsilesional). We investigated in 13 right‐brain‐damaged patients with left spatial neglect and perseverative behaviour whether and how different densities of horizontal targets modulated omission and perseverative errors. We found that the density of targets modulated the patients’ distribution of neglect (area of omission), but not its extent, as indexed by the percentage of omissions. Specifically, the area of omissions tightened when target density increased leftwards. On the other hand, target density did not affect the distribution of perseverative behaviour (area of perseveration), as well as its extent, as indexed by the percentage of perseverations. Correlation analyses showed that both the extent and the distribution of omissions were positively correlated to clinical measures of spatial neglect. Conversely, perseverations did not show such a correlation. These findings support the view that two different pathological mechanisms might be involved in left spatial neglect and in ipsilesional perseverative behaviour.     

Personality and Optimal Experience in Adolescence: Implications for Well-Being and Development

Past research has repeatedly identified relations between optimal experience—or flow—and well-being across the lifespan. In the attempt to identify the conditions favoring this experience, some studies took into account personality traits. While most of them operationalized flow in terms of intensity, we presently focused on perceived occurrence versus absence of flow. Specifically, we investigated the relations between flow occurrence, hedonic and eudaimonic well-being, activities associated with flow, and personality in adolescence. A group of 408 Italian teenagers (mean age = 17.31; SD = 1.13) were administered Flow Questionnaire, Satisfaction with Life Scale, Positive and Negative Affect Schedule, Psychological Well-being Scales, and the Big Five Questionnaire. Participants reporting optimal experience in their lives were compared with those not reporting it. Results showed that adolescents experiencing flow reported higher satisfaction with life, hedonic balance, and psychological well-being than their counterparts. Findings from logistic regression analyses further showed that openness to experience was the sole personality factor predicting flow occurrence, and that no personality factors were predictive of type of activities adolescents associated with flow. Findings point to the promotion of optimal experience among adolescents through the support of curiosity and openness to new experiences in engaging opportunities for action. They further call for the development of an integrated model taking into account both individual predispositions and social and cultural factors in well-being promotion.     

Appetitive and aversive olfactory learning induce similar generalization rates in the honey bee

Appetitive and aversive learning drive an animal toward or away from stimuli predicting reinforcement, respectively. The specificity of these memories may vary due to differences in cost–benefit relationships associated with appetitive and aversive contexts. As a consequence, generalization performances may differ after appetitive and aversive training. Here, we determined whether honey bees show different rates of olfactory generalization following appetitive olfactory conditioning of the proboscis extension response, or aversive olfactory conditioning of the sting extension response. In both cases, we performed differential conditioning, which improves discrimination learning between a reinforced odor (CS+) and a non-reinforced odor (CS?) and evaluated generalization to two novel odors whose similarity to the CS+ and the CS? was different. We show, given the same level of discriminatory performance, that rates of generalization are similar between the two conditioning protocols and discuss the possible causes for this phenomenon.
