An exploratory analysis of head-tilting in dogs

Animal Cognition - Little is known about head-tilts in dogs. Based on previous investigations on the head turning and the lateralised brain pattern of human speech processing in dogs, we...     

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

     

A method for quantifying focused versus overview behavior in AOI sequences

We present a new measure for evaluating focused versus overview eye movement behavior in a stimulus divided by areas of interest. The measure can be used for overall data, as well as data over time. Using data from an ongoing project with mathematical problem solving, we describe how to calculate the measure and how to carry out a statistical evaluation of the results.     

Does retrieval strategy disruption cause general and specific collaborative inhibition?

The purpose of the experiment on collaborative memory was to investigate if the collaborative inhibition is due to collaborating pair's disruption of each others' retrieval strategies (the retrieval strategy disruption hypothesis, RSD). The participants' (N = 36) task was to recall a list of 60 words individually and collaboratively. Retrieval strategies were manipulated by presenting word lists organised either by categories or by country of origin and adoption of retrieval strategies were examined by the adjusted ratio of clustering score. Half of the dyads received word lists organised by the same strategy and half of the dyads received word lists organised by different strategies. The results revealed a main effect of collaboration, i.e., collaborative recalled items were significantly fewer than the sum of the non-redundant individually recalled items. Both conditions (same strategies vs different strategies) suffered to the same extent from collaboration, which did not support the RSD hypothesis. However, focusing on words recalled individually but not collaboratively, dyads with different strategies, as predicted by the RSD, forgot more items during collaboration than did dyads with the same strategy. Additional results suggest that collaborative forgetting is mainly manifested by forgetting of non-overlapping items (as measured by individual recalls).     

Rethinking Emancipation,Rethinking Education

In this paper I discuss the possibility of the idea of emancipation within an educational philosophy that does not accept schooling as its first premise. The first part of the paper will take Sweden as an example of an educational state defined through educational policies such as life long learning, accountability and evidence-based research, and argue that these words are only meaningful within the myth of schooling and not in a language of education/emancipation. The second part of the paper discusses different but related conceptions of emancipation by exploring its ambiguous nature. In the third part of the paper I specify the role and place of emancipation within a philosophy of education that seeks to articulate its social value.     

Who Voted for Whom? Comparing Supporters of Obama and McCain on Value Types and Personality Traits

This study investigates the personalities and values of Obama and McCain supporters in the 2008 election. A total of 278 American participants completed the Big Five Inventory and the Portrait Values Questionnaire along with demographic items. For value types, Obama supporters were more likely to endorse universalism values and less likely to endorse tradition, conformity, and security values compared with McCain supporters. With regard to personality traits, Obama supporters scored higher on agreeableness and lower on conscientiousness than did McCain supporters. As predicted, logistic regression revealed that values were better predictors of voting preference than were personality traits. These findings demonstrate the importance of individual differences in political preferences and are discussed with regard to findings in other cultures.     

Adding part-of-speech information to the SUBTLEX-US word frequencies

The SUBTLEX-US corpus has been parsed with the CLAWS tagger, so that researchers have information about the possible word classes (parts?\of?\speech, or PoSs) of the entries. Five new columns have been added to the SUBTLEX-US word frequency list: the dominant (most frequent) PoS for the entry, the frequency of the dominant PoS, the frequency of the dominant PoS relative to the entry??s total frequency, all PoSs observed for the entry, and the respective frequencies of these PoSs. Because the current definition of lemma frequency does not seem to provide word recognition researchers with useful information (as illustrated by a comparison of the lemma frequencies and the word form frequencies from the Corpus of Contemporary American English), we have not provided a column with this variable. Instead, we hope that the full list of PoS frequencies will help researchers to collectively determine which combination of frequencies is the most informative.
