Testing the age related differentiation hypothesis through the Wechsler’s scales

According to the age differentiation hypothesis (ADH), g becomes increasingly invested in specific abilities with age: with increasing age, g should account for a decreasing proportion of the variance in any particular cognitive test. However, there is no conclusive evidence concerning this important topic. Data from the Italian, Spanish, and American standardisation samples of the WPPSI and the WISC-R were analysed in the present study for testing the ADH. No changes in the proportion of variance associated with g in the 4–16 age range were found. This pattern does not change depending on the country. Therefore, the ADH is rejected: g seems to be very stable across age, and, thus, it seems to be an equally important component of intelligence test performance from early childhood to late adolescence.     

Impact of emotional appeal on non-profit advertising: A neurophysiological analysis

The number of Non-Profit Organisations (NPOs) has increased in the past years, and they rely on advertising to communicate their causes. Although the effectiveness of NPO advertising has been studied previously, there is still no consensus about which appeal (emotionally positive or negative) increases its effectiveness. On the other hand, the most prevalent research approaches to NPO advertising are traditional research methodologies based on declarative techniques. So, the purpose of this study is to identify which appeal (positive or negative) in NPO advertising is more effective at the three levels of effectiveness (perceptual or communicational effectiveness, psychological or attitudinal effectiveness and behavioural effectiveness), providing a new approach based on the analysis of consumers' unconscious responses to advertising. We conducted an experiment with 113 participants whose neurophysiological responses were evaluated through electroencephalogram (EEG) and eye tracking (ET) while they watched NPO advertisements with a randomly assigned emotional appeal (positive or negative). In addition, a survey revealed behavioural responses. The results showed that considering the psychological or attitudinal effectiveness, positively framed ads are more effective, as there is a positive effect on attitudes towards the ad and a higher positive emotional valence. On the other hand, in perceptual effectiveness, where attention is considered an important variable, the negatively framed ads showed more significant time in the area of interest (AOI) of the image area of the ad, and longer time in the AOI text was observed for positively framed ads. Furthermore, regarding behavioural effectiveness, negatively framed ads seem more effective in eliciting actual donations. The results suggest that a positive appeal is more effective in generating a more positive attitude and a positive emotional valence towards the advertisement, which could benefit the NPO in the long term. But a negative appeal is more effective if the goal is to achieve immediate donations.     

Methodological naturalism and epistemic internalism

Epistemic naturalism holds that the results or methodologies from the cognitive sciences are relevant to epistemology, and some have maintained that scientific methods are more compatible with externalist theories of justification than with internalist theories. But practically all discussions about naturalized epistemology are framed exclusively in terms of cognitive psychology, which is only one of the cognitive sciences. The question addressed in this essay is whether a commitment to naturalism really does favor externalism over internalism, and we offer reasons for thinking that naturalism in epistemology is compatible with both internalist and externalist conceptions of justification. We also argue that there are some distinctively internalist aims that are currently being studied scientifically and these notions, and others, should be studied by scientific methods. This essay is dedicated to Deborah Mayo, who has long advocated using error statistical techniques to analyze and resolve epistemological puzzles in the philosophy of science. This essay follows the same spirit by advocating that computational concepts and techniques be applied within the heart of traditional, analytic epistemology.     

Therapists' verbal behavior category system

This paper presents the theoretical and methodological basis of a therapist's verbal behavior category system that allows us to study clinical psychologists' language from a functional-analytic framework and with a rigorous observation method. The procedure to develop the coding system is explained in detail from a very early stage of exploratory observation, to the systematic observation through the use of The Observer XT software. An analysis of intra- and inter-rater reliability using the kappa coefficient and taking into account the factors that affect the values of Cohen's index was carried out. Results show high levels of observer accuracy (between approximately 87% and 93%) that justify the application of this category system to study therapists' verbal behavior in session.     

Cognitive flexibility in preschoolers: the role of representation activation and maintenance

Preschoolers' lack of cognitive flexibility has often been attributed to perseverative processing. This study investigates alternative potential sources of difficulty such as deficits in activating previously ignored information and in maintaining currently relevant information. In Experiment 1, a new task tapping attentional switching was designed to isolate the difficulty of overriding an initial representation, that is, perseverative processing ('Perseveration' version), and the difficulty of activating a previously ignored representation, that is, activation deficit ('Activation-deficit' version). Three-year-olds' performance suggested that inflexibility may primarily stem from an activation deficit. Control experiments confirmed that the difficulty of the 'Activation-deficit' version could not be attributed to the effect of attraction to novelty. In Experiment 2, 'distraction' errors, alleged to reflect a failure to maintain a relevant representation, and 'perseverative' errors were distinguished. The results highlighted the important role of representation maintenance in flexibility. The present study indicates that preschoolers' lack of cognitive flexibility is multi-determined and prompts us to reconsider the role of perseveration.     

Priming the mental time-line: effects of modality and processing mode

The notion of a mental time-line (i.e., past corresponds to left and future corresponds to right) supports the conceptual metaphor view assuming that abstract concepts like “time” are grounded in cognitively more accessible concepts like “space.” In five experiments, we further investigated the relationship between temporal and spatial representations and examined whether or not the spatial correspondents of time are unintentionally activated. We employed a priming paradigm, in which visual or auditory prime words (i.e., temporal adverbs such as yesterday, tomorrow) preceded a colored square. In all experiments, participants discriminated the color of this square by responding with the left or the right hand. Although the temporal reference of the priming adverb was task irrelevant in Experiment 1, visually presented primes facilitated responses to the square in correspondence with the direction of the mental time-line. This priming effect was absent in Experiments 2, 3, and 5, in which the primes were presented auditorily and the temporal reference of the words could be ignored. The effect, however, emerged when attention was oriented to the temporal content of the auditory prime words in Experiment 4. The results suggest that task demands differentially modulate the activation of the mental time-line within the visual and auditory modality and support a flexible association between conceptual codes.     

The Use of Mental Health Services Among Victims of Partner Violence on College Campuses

The present study investigated the relationship between past victimization of different types of intimate partner violence (IPV; physical, psychological, and sexual) and the likelihood of using mental health services. Results indicate 86% of participants reported experiencing some form of IPV, but only 16% of those victims used mental health services to address emotional problems. The participants reported embarrassment, expense, ineffectiveness, and social stigma as the most prominent barriers to seeking help from a mental health professional. The study also found that participants who experienced physical and psychological IPV, but not sexual IPV, reported using mental health services. Sexual IPV may elicit different barriers in help-seeking behaviors. Implications for college IPV prevention programs and mental health services are discussed.     

Conscientiousness,Its Facets,and the Prediction of Job Performance Ratings: Evidence against the narrow measures

This study empirically tested the predictions of the three basic perspectives on the bandwidth debate about the relationship between personality and job performance, regarding the validity of conscientiousness and its facets. The sample consisted of 226 police officers. Conscientiousness and three facets (order, industriousness, and self‐control) were correlated with three performance criteria (overall job performance, task performance, and orderliness). A Schmid–Leiman transformation made it possible to residualize the variance of the facets and to isolate their unique contribution to the prediction of performance measures. The results showed that conscientiousness predicted the three criteria (true validities of.25,.28 and.37, respectively) and that the facets neither predicted job performance nor showed incremental validity over conscientiousness. Finally, the implications of the findings for theory and practice are commented on, and future research is suggested.
