Avoiding and Alternate Possibilities

Greg Janzen has recently criticised my defence of Frankfurt’s counterexample to the Principle of Alternate Possibilities by arguing that Jones avoids killing Smith in the counterfactual scenario. Janzen’s argument consists in introducing a new thought-experiment which is supposed to be analogous to Frankfurt’s and where the agent is supposed to avoid A-ing. Here I argue that Janzen’s argument fails on two counts, because his new scenario is not analogous to Frankfurt’s and because the agent in his new scenario does not avoid A-ing.     

A novel paradigm reveals the role of reentrant visual processes in object substitution masking

Object substitution masking (OSM) occurs when an initial display of a target and mask continues with the mask alone, creating a mismatch between the reentrant hypothesis, triggered by the initial display, and the ongoing low-level activity. We tested the proposition that the critical factor in OSM is not whether the mask remains in view after target offset, but whether the representation of the mask is sufficiently stronger than that of the target when the reentrant signal arrives. In Experiment 1, a variable interstimulus interval (ISI) was inserted between the initial display and the mask alone. The trailing mask was presumed to selectively boost the strength of the mask representation relative to that of the target. As predicted, OSM occurred at intermediate ISIs, at which the mask was presented before the arrival of the reentrant signal, creating a mismatch, but not at long ISIs, at which a comparison between the reentrant signal and the low-level activity had already been made. Experiment 2, conducted in dark-adapted viewing, ruled out the possibility that low-level inhibitory contour interactions (metacontrast masking) had played a significant role in Experiment 1. Metacontrast masking was further ruled out in Experiment 3, in which the masking contours were reduced to four small dots. We concluded that OSM does not depend on extended presentation of the mask alone, but on a mismatch between the reentrant signals and the ongoing activity at the lower level. The present results place constraints on estimates of the timing of reentrant signals involved in OSM.     

Measuring psychological mindedness: validity,reliability, and relationship with psychopathology of an Italian version of the Balanced Index of Psychological Mindedness

Psychological mindedness (PM) is an underinvestigated, but important construct in psychoanalytic psychotherapy research and practice. It refers to the interest in and ability for reflecting on one's thoughts and feelings, and it represents an important precondition for insight-oriented therapy to be successful. Notwithstanding, very few instruments are available to measure PM. The current investigation aimed at evaluating the validity and reliability of the Balanced Index of Psychological Mindedness (BIPM; Nyklí?ek & Denollet, 2009, Psychological Assessment, 21, 32–44), a brief measure of PM. In a first study, factor structure, internal consistency, and concurrent validity of the BIPM were tested, along with the relationship between the BIPM and a continuous measure of general distress, using a sample of 298 Italian students. In a second study, test-retest stability analyses were completed using a new, different, Italian student sample (N = 58). In a third study, the BIPM scores of a clinical sample with diagnosis of mood spectrum disorders (N = 30) were compared to those of an age-, gender-, and education-matched nonclinical sample. Overall, results indicate that the BIPM is a psychometrically sound instrument that can be used in clinical practice to obtain rapid information about the client's mentalization skills and assess PM.     

Divergent Thinking and Age-Related Changes

Aging can affect cognition in different ways. The extent to which aging affects divergent thinking is unclear. In this study, younger and older adults were compared at the performance on the Torrance Test of Creative Thinking in visual and verbal form. Results showed that older adults can think divergently as younger participants, although they produce fewer visual ideas. This finding involves implications for active aging, given that also older adults can be still capable to produce original ideas and improve living conditions surrounding them.     

Priming Effects and Free Will

Abstract

I argue that the empirical literature on priming effects does not warrant nor suggest the conclusion, drawn by prominent psychologists such as J. A. Bargh, that we have no free will or less free will than we might think. I focus on a particular experiment by Bargh – the ‘elderly’ stereotype case in which subjects that have been primed with words that remind them of the stereotype of the elderly walk on average slower out of the experiment’s room than control subjects – and I show that we cannot say that subjects cannot help walking slower or that they are not free in doing do. I then illustrate how these cases can be reconciled and normalized within a Davidsonian theory of action to show that, in walking slower, subjects are acting intentionally. My argument applies across various experiments, including those of goal priming. In the final section I argue that the only cases in which priming effects are efficacious are so-called Buridan cases.     

Lexicality and Stimulus Length Effects in Italian Dyslexics: Role of the Overadditivity Effect

The effect of lexicality and stimulus length was studied in 32 third- and fourth-grade Italian dyslexics and in 86 age-matched controls. A visual lexical decision task was used. As proposed by Faust et al. (1999) Faust, M. E., Balota, D. A., Spieler, D. H. and Ferraro, F. R. 1999. Individual differences in information-processing rate and amount: Implications for group differences in response latency. Psychological Bulletin, 125: 777–799. [INFOTRIEVE][CROSSREF][CSA][Crossref], [PubMed], [Web of Science ®] , [Google Scholar], the results were analyzed in terms of raw reaction time (RT) data and using the z-score transformation to control for the presence of overadditivity effects. In terms of RTs, dyslexics showed a larger difference between words and nonwords (lexicality effect) and between short and long stimuli (length effect) than proficient readers. When data were transformed into z scores, only the group by length interaction remained significant while that with lexicality vanished. This pattern indicates that stimulus length has a specific role in Italian dyslexics’ reading deficit; in contrast, slowness in responding to nonwords was not specific but was interpreted as one aspect of dyslexics’ general inability to deal with alphabetical material (overadditivity effect).     

The Factor Structure of Effortful Control and Measurement Invariance Across Ethnicity and Sex in a High-Risk Sample

Measurement invariance of a one-factor model of effortful control (EC) was tested for 853 low-income preschoolers (M age = 4.48 years). Using a teacher-report questionnaire and seven behavioral measures, configural invariance (same factor structure across groups), metric invariance (same pattern of factor loadings across groups), and partial scalar invariance (mostly the same intercepts across groups) were established across ethnicity (European Americans, African Americans and Hispanics) and across sex. These results suggest that the latent construct of EC behaved in a similar way across ethnic groups and sex, and that comparisons of mean levels of EC are valid across sex and probably valid across ethnicity, especially when larger numbers of tasks are used. The findings also support the use of diverse behavioral measures as indicators of a single latent EC construct.     

Vocational and overall identity: A person-centered approach in Italian university students

Establishing a vocational and overall identity involve defining life altering plans and associated commitments to pursue and achieve them and are, therefore, among the most central aspects of the developmental tasks of late adolescents and emerging adults. In the Italian context, young adults' opportunity to develop coherent and fulfilling future plans are strongly threated by the current distressed economic climate in Italy. Assuming these features of the Italian context can produce specific identity patterns, the present study aimed to contribute to the understanding of overall and vocational identity processes in Italian emerging adults and to explore the relationship between the two domains of identity using a person-centered approach. The study is composed of two parts. The first study assessed the psychometric properties of the Italian version of the Vocational Identity Status Assessment (VISA) in a sample of university students from Italy (N = 560). The second study included a cluster analytic approach in order to explore the configuration of both vocational and overall identity domains. The findings suggest that the Italian version of the VISA is a promising tool for assessing vocational identity dimensions in the Italian context. Furthermore, unlike the previous literature, we found different patterns of vocational and overall identity in Italian university students. The findings suggest that the current socio-economic Italian situation may be hindering students' progress toward achieving a vocational identity, especially for freshmen.
