Gödel,Kant, and the Path of a Science

Gödel's philosophical views were to a significant extent influenced by the study not only of Leibniz and Husserl, but also of Kant. Both Gödel and Kant aimed at the secure foundation of philosophy, the certainty of knowledge and the solvability of all meaningful problems in philosophy. In this paper, parallels between the foundational crisis of metaphysics in Kant's view and the foundational crisis of mathematics in Gödel's view are elaborated, especially regarding the problem of finding the “secure path of a science” for both mathematics and philosophy. Gödel's temporal subjectivism and metaphysical conceptual objectivism are presented as positively or negatively motivated by Kant's viewpoints. A remark on Gödel's collapse of modalities (in accordance with the collapse of objective time) is added.     

When it matters how you pronounce it: the influence of regional accents on job interview outcome

The visual dimension has featured prominently in person perception in the last 25 years. Alone, this dimension cannot give the complete 'picture' of others because language and speech (i.e., the auditory dimension) are also highly informative. Social-cognition research investigates the role of auditory information for impression formation. In a series of experiments, we tested perceived competence, hirability, and socio-intellectual status of different targets based on their regional accents. Given identical content of statements in different conditions of an alleged job interview, regional German accents (Saxon, Bavarian, and Berlin) resulted in lower perceived competence and hirability than standard German, even though the Bavarian accent at the same time resulted in higher ratings of socio-intellectual status compared to other regional accents (Experiment 1). These findings were confirmed when using a broader population sample and a 'matched guise' technique (Experiment 2). Our findings indicate that regional accents, similar to faces, can be very powerful in creating differentiated pictures of individuals.     

When self-destructive thoughts flash through the mind: Failure to meet standards affects the accessibility of suicide-related thoughts

When individuals realize that they fail to attain important standards or expectations, they may be motivated to escape the self, which could lead thoughts of suicide to become more accessible. Six studies examined this hypothesis, mainly derived from escape theory (Baumeister, 1990). The results indicated that whenever individuals realize that they fail to attain an important standard, they experience increased accessibility of suicide-related thoughts (Studies 1-6). In line with the idea that such effects reflect motivations to escape from negative self-awareness, they were especially pronounced when associated with high levels of self-consciousness and escapist motivations (Study 1) and with a large discrepancy between self and standards (Studies 2-4). Moreover, failure to attain standards increased suicide-thought accessibility along with the desire for an altered state of consciousness (Study 5). Finally, increases in suicide-thought accessibility after failure were associated with simultaneous increases in accessibility of general concepts related to escape (Study 6). Implications of these findings for escape and terror management theories are discussed.     

Correction to urošević et Al. (2012)

Reports an error in "Longitudinal Changes in Behavioral Approach System Sensitivity and Brain Structures Involved in Reward Processing During Adolescence" by Sne?ana Uro?evi?, Paul Collins, Ryan Muetzel, Kelvin Lim and Monica Luciana (Developmental Psychology, Advanced Online Publication, Mar 5, 2012, np). Figure 2 was distorted in production. The correct version is presented in the erratum. (The following abstract of the original article appeared in record 2012-05404-001.) Adolescence is a period of radical normative changes and increased risk for substance use, mood disorders, and physical injury. Researchers have proposed that increases in reward sensitivity (i.e., sensitivity of the behavioral approach system [BAS]) and/or increases in reactivity to all emotional stimuli (i.e., reward and threat sensitivities) lead to these phenomena. The present study is the first longitudinal investigation of changes in reward (i.e., BAS) sensitivity in 9- to 23-year-olds across a 2-year follow-up. Support was found for increased reward sensitivity from early to late adolescence, and evidence was found for decline in the early 20s. This decline is combined with a decrease in left nucleus accumbens (Nacc) volume, a key structure for reward processing, from the late teens into the early 20s. Furthermore, we found longitudinal increases in sensitivity to reward to be predicted by individual differences in the Nacc and medial orbitofrontal cortex (OFC) volumes at baseline in this developmental sample. Similarly, increases in sensitivity to threat (i.e., behavioral inhibition system sensitivity) were qualified by sex, with only females participants experiencing this increase, and predicted by individual differences in lateral OFC volumes at baseline.

Longitudinal changes in behavioral approach system sensitivity and brain structures involved in reward processing during adolescence

Grouping illumination frameworks

According to Koffka (1935), the lightness of a target surface is determined by the relationship between the target and the illumination frame of reference to which it belongs. However, each scene contains numerous illumination frames, and judging each one separately would lead to an enormous amount of computing. Grouping those frames that are in the same illumination would simplify the computation. We report a series of experiments demonstrating that nonadjacent regions of the visual field under the same illumination level are perceptually grouped together and function, to some extent, as a single framework. A small coplanar group of patches under its own illumination exhibits compression of perceived range of gray shades. We obtained the reduction in compression in the presence of an identically illuminated 25-patch Mondrian tableau mounted nearby the coplanar group. The influence of the Mondrian display was reduced when it was (a) moved laterally away from the test display, (b) moved farther back in depth from the test display, or (c) rotated to a different orientation.     

Did curiosity kill the cat? Evidence from subjective well-being in adolescents

The purpose of this study was to explore the relations between trait curiosity and the well-being of adolescents. The differences between adolescents with high, average and low trait curiosity on a number of subjective well-being (SWB) and distress measures have been examined. The sample consisted of 408 high school students, with an average age of 16.6 years. The results showed that adolescents high in trait curiosity have higher levels of life satisfaction and positive affect and greater sense of purpose in life and hope than adolescents with both low and average curiosity. Contrary to significant differences on positive well-being measures, there were no robust differences between adolescents with high, average and low curiosity in distress. The findings of this research indicated that curiosity is a specific predictor of positive well-being and gave support to the two continua model of mental health, which view positive and negative well-being as relatively independent constructs.     

Practice and some methodological problems in unidimensional information transmission

Fifty circular lights differir.g in diameter from 4 to 53 cm and increasing by 1 cm were presented 135 times each to five Ss who were asked to identify each circle. Presentations were in random order. Indices of information transmission (T), response equivocation H S(R), and response uncertainty H(R) were calculated for different phases of the experiment for individual and pooled (across Ss) responses. Results have shown systematic rising of transmission and lowering of H S(R), while H(R) remained almost constant. All transmission indices calculated from pooled responses were systematically lower than comparable indices calculated from individual responses. Individual and pooled T values calculated from all responses given during the experiment were not representative for the level of identification performance at the end of the experiment. Conclusions were reached that (1) channel capacity indices should not be calculated from all individual responses given during the experiment or from pooled responses of different Ss, and (2) indices of channel capacity should be calculated only after the performance of Ss has reached a final and stable level, which means after enough repetitions of each stimulus.
