The relationship between need for closure and memory for schema-related information among younger and older adults

Two studies were conducted to examine the relationships among need for closure (NFC) and schematic information processing in younger and older adults. The results show increased NFC to be associated with less schematic processing (i.e., less memory for schema-consistent items, and more memory for schema-irrelevant items, out of all items memorized correctly), among older than younger adults. The findings of the studies are interpreted as demonstrating the age-associated deficit in information processing consistent with the level of NFC. Moreover, the results indicate that positive mood may play a role in facilitating information processing consistent with the level of NFC among older and younger adults. Finally, we present a framework for predicting when older adults will and will not effectively use schematic processing, considered a compensatory strategy for decline in cognitive abilities.     

Reciprocal relationships between three aspects of physical self-concept,vigorous physical activity,and lung function: A longitudinal study among late adolescents

ObjectivesThis prospective study, of older adolescents, investigated relationships between three aspects of physical self-concept, vigorous physical activity and lung function. In particular, physical competence, general appearance evaluations and body areas satisfaction were expected to predict subsequent physical activity, which, in turn, was expected to explain variation in lung function. In line with the reciprocal effect model, bi-directorial relationships were also tested. Gender was expected to moderate hypothesized relationships.DesignA longitudinal design, with three measurement points (baseline, 2-month follow-up, and 14-month follow-up) was employed.Method551 late adolescents (15–18 years old) provided self-reported data on physical activity, physical competence, body areas satisfaction, and appearance evaluation. Body weight, height, and a lung function index (forced expiratory volume in 1 s, FEV₁) were measured at baseline and at the 14-month follow-up.ResultsModerated mediation analyses indicated that physical competence at baseline predicted vigorous physical activity (2-month follow-up) among young men and women. Baseline body satisfaction and appearance evaluation were also related to vigorous physical activity (2-month follow-up) and this relationship was stronger for men. Vigorous physical activity predicted FEV₁ (14-month follow-up) and this relationship was stronger among women. The reciprocal pattern of relationships was not confirmed.ConclusionsFindings suggest that health promoting interventions should focus particularly on vigorous physical activity among young women, for example by boosting their physical competence.     

Addicted to answers: Need for cognitive closure and the endorsement of conspiracy beliefs

Conspiracy theories offer simple answers to complex problems by providing explanations for uncertain situations. Thus, they should be attractive to individuals who are intolerant of uncertainty and seek cognitive closure. We hypothesized that need for cognitive closure (NFCC) should foster conspiracy beliefs about events that lack clear official explanations, especially when conspiracy theories are temporarily salient. In Experiment 1, NFCC positively predicted the endorsement of a conspiracy theory behind the refugee crisis, especially when conspiratorial explanations were made salient. Experiment 2 showed that when conspiratorial explanations were made salient, NFCC positively predicted beliefs in conspiracies behind a mysterious plane crash. However, the link between NFCC and beliefs in conspiratorial explanations was reversed in the case of a plane crash with an official, non‐conspiratorial, explanation for the accident. In conclusion, people high (vs. low) in NFCC seize on conspiratorial explanations for uncertain events when such explanations are situationally accessible.     

The negative compatibility effect with nonmasking flankers: a case for mask-triggered inhibition hypothesis

Visual targets which follow a prime stimulus and a mask can be identified faster when they are incompatible rather than compatible with the prime (negative compatibility effect--NCE). According to the self-inhibition hypothesis, the initial activation of the motor response is elicited by the prime based on its identity. This activation leads to benefits for compatible trials and costs for incompatible trials. This motor activation is followed by an inhibition phase, leading to an NCE if perceptual evidence of the prime is immediately removed by the mask. The object-updating and mask-triggered inhibition hypotheses emphasize the role of the mask content (i.e. whether the mask possesses target-like features). We show that the NCE may appear even if nonmasking neutral flankers are presented instead of a mask. Moreover, although with target-like flankers the NCE is larger, it occurred if flankers and targets are built from dissimilar elements. Therefore, masks/flankers can evoke an inhibition phase independently of whether or not they remove evidence for the prime and whether they are similar to the targets.     

Temporal-order judgments and reaction time for stimuli of different modalities

Summary Reaction times and the relative latency evaluated by the temporal-order-judgment method for two stimuli of different modalities (visual and auditory) were measured. The difference between reaction times for visual and auditory stimuli was about 40 ms. The relative latency was slightly shorter, however; in conflict with Rutschmann and Link's (1964) previous result, the auditory stimulus must be delayed to be perceived simultaneously with the visual one.     

Assessing inhibitory control in early-stage Alzheimer's and Parkinson's disease using the Hayling Sentence Completion Test

The ability to inhibit irrelevant information is essential for coping with the demands of everyday life. Inhibitory deficits are present in all stages of dementia and commonly observed in people with Parkinson's disease (PwPD). Inhibition is frequently tested with the Stroop test, but this may lack ecological validity. This study investigates inhibitory control in people with Alzheimer's disease dementia (PwD) and PwPD using the Hayling Sentence Completion Test (HSCT), which aspires to be a more ecologically valid task. A total of 117 people completed the HSCT, a test where participants have to complete a sentence with an unrelated word. The sample comprised 30 PwD, 33 PwPD, and 54 healthy older controls. We compared response times and the number and type of errors across the three groups. Completion time in Part B (Inhibition) did not distinguish between PwD, PwPD, and controls when controlling for the initiation speed, but a higher proportion of Category A errors (producing a word that fits the sentence when instructed otherwise) was a unique characteristic of inferior performance in PwD and PwPD. While not part of the standard test scoring protocol, controlling for the initiation speed and distinguishing between speed and accuracy in test performance appear to be essential for accurate evaluation of the inhibitory control in HSCT in older people. The findings suggest that the HSCT may be sensitive to verbal suppression deficits and may provide insight into inhibitory control in PwD and PwPD.     

Quality of Life and Optimism in Patients with Morphea

Despite extensive knowledge about quality of life of people suffering from dermatological diseases, data on patients with morphea are scarce. The aim of our study was to compare the quality of life of healthy controls and morphea patients, as well as to determine the correlation of this variable with the level of dispositional optimism. The study included 47 patients with morphea and 47 healthy controls, matched for gender and age. Cantril’s Ladder and Life Orientation Test-Revised were used to assess the levels of life satisfaction and dispositional optimism, respectively. LoSSI was used for the objective assessment. The anticipated level of life quality and the level of dispositional optimism were statistically significantly lower in morphea patients (p?=?0.032 and p?=?0.014, respectively) when compared to controls. There were no differences in the assessment of current (p?=?0.168) and past (p?=?0.318) levels of life quality. Also, we proved that type of morphea did not differentiate the current (p?=?0.175), past (p?=?0.620) and future (p?=?0.356) assessment of the quality of life. In the group of morphea patients there was a statistically significant correlation between the level of dispositional optimism and current (p?=?0.002, r?=?0.43), as well as anticipated (p?r?=?0.57) levels of life quality. Current level of life quality of healthy controls and morphea patients is comparable, whereas the latter anticipate their future life situation to be significantly worse than the former. Higher level of life satisfaction correlates with higher level of optimism.
