The effect of cultural values on pro-environmental attitude in the context of travel mode choice: A hierarchical approach

The cultural theory explains social behavior through four elementary types of cultural values consisting of hierarchy, individualism, egalitarianism, and fatalism. The knowledge of how these values influence attitudes and behaviors specifically pertain to the environment is limited. Understanding individuals’ values and attitudes should be addressed in travel mode choice based on possible impacts of transportation on the environment. This study investigates the effect of cultural values on pro-environmental attitude and the influence of this attitude on travel mode choice in light of a hierarchical latent choice model. The model is estimated using data from a random sampling in CBD (Central Business District) of Tehran, Iran. The pro-environmental attitude, which is postulated to be affected by cultural values, is considered as the latent variable directly affecting travel mode choice. The cultural values drivers of pro-environmental attitude have been seen in a hierarchical structure. The estimated results show that hierarchical cultural tendency has the strongest and positive effect on being pro-environmental. Also, individualistic culture indicates a positive trend in being pro-environmental. On the other side, people with egalitarianism value tend to report an orientation towards pro-environmental attitude. Moreover, pro-environmental attitude increases the utility of public and active modes of transportation and a negative significant effect is found on the utility of private car and motorcycle.     

Servant Leadership Behaviour Scale: A hierarchical model and test of construct validity

Servant leadership is widely believed to be a multidimensional construct. However, existing measures of servant leadership typically suffer from highly correlated dimensions, raising concerns over discriminant validity. We set out in this study to examine the dimensionality of the hypothesized six-factor Servant Leadership Behaviour Scale (SLBS) and validate a hierarchical model of servant leadership. Using structural equation modelling, convergent and discriminant validity of the higher-order servant leadership construct was examined in relation to measures of character-related behaviour, Machiavellian leadership orientation, and social desirability. Our findings suggest that the SLBS assesses a single, higher-order construct of servant leadership with evidence of construct validity and absence of social desirability bias. The high correlation between servant leadership and character-related behaviour supports our expectation that servant leadership reflects in large part the character strength of the leader.     

Hearing living symbols and nonliving icons: Category specificities in the cognitive processing of environmental sounds

The neurocognitive processing of environmental sounds and linguistic stimuli shares common semantic resources and can lead to the activation of motor programs for the generation of the passively heard sound or speech. We investigated the extent to which the cognition of environmental sounds, like that of language, relies on symbolic mental representations independent of the acoustic input. In a hierarchical sorting task, we found that evaluation of nonliving sounds is consistently biased toward a focus on acoustical information. However, the evaluation of living sounds focuses spontaneously on sound-independent semantic information, but can rely on acoustical information after exposure to a context consisting of nonliving sounds. We interpret these results as support for a robust iconic processing strategy for nonliving sounds and a flexible symbolic processing strategy for living sounds.     

Learnability of embedded syntactic structures depends on prosodic cues

The ability to process center-embedded structures has been claimed to represent a core function of the language faculty. Recently, several studies have investigated the learning of center-embedded dependencies in artificial grammar settings. Yet some of the results seem to question the learnability of these structures in artificial grammar tasks. Here, we tested under which exposure conditions learning of center-embedded structures in an artificial grammar is possible. We used naturally spoken syllable sequences and varied the presence of prosodic cues. The results suggest that mere distributional information does not suffice for successful learning. Prosodic cues marking the boundaries of the major relevant units, however, can lead to learning success. Thus, our data are consistent with the hypothesis that center-embedded syntactic structures can be learned in artificial grammar tasks if language-like acoustic cues are provided.     

The role of prior exposure in the capture of attention by items in working memory

The Biased Competition Model (BCM) suggests both top-down and bottom-up biases operate on selective attention (e.g., Desimone & Duncan, 1995). It has been suggested that top-down control signals may arise from working memory. In support, Downing (2000) found faster responses to probes presented in the location of stimuli held vs. not held in working memory. Soto, Heinke, Humphreys, and Blanco (2005) showed the involuntary nature of this effect and that shared features between stimuli were sufficient to attract attention. Here we show that stimuli held in working memory had an influence on the deployment of attentional resources even when: (1) It was detrimental to the task, (2) there was equal prior exposure, and (3) there was no bottom-up priming. These results provide further support for involuntary top-down guidance of attention from working memory and the basic tenets of the BCM, but further discredit the notion that bottom-up priming is necessary for the effect to occur.

This longitudinal study focused on the causal relationships between self-concept, locus of causality, and academic achievement. The subjects were 212 male and 213 female students at a prestigious secondary school in the central Philippines. Analysis of the panel data indicated that no single network of causal dominance may exist for males and females but did support Weiner's (1979) causal attribution theory in finding that locus of causality was causally predominant over self-concept.     

The basic components of adult playfulness and their relation with personality: The hierarchical factor structure of seventeen instruments

The primary aim of this study was testing the structure of adult playfulness in a joint analysis of seventeen questionnaires and testing the relation of the factors with the big five personality traits. A sample of 244 adults completed the questionnaires and a five factor-solution fit the data best; i.e., (a) Humorousness; (b) Cheerfulness–Uninhibitedness; (c) Expressiveness; (d) Other-directedness; and (e) Intellectuality–Creativity. Correlation analyses (bivariate, canonical) and regression analyses indicated strong overlap of the broader personality factors and the Cheerfulness–Uninhibitedness-factor (extraversion and emotional stability) as well as the Expressiveness-factor (extraversion). The study contributes towards a better understanding of the structure of playfulness in questionnaires developed for adults. Implications for future research are discussed.     

Abducted by Bayesians?

This paper discusses the role of theoretical notions in making predictions and evaluating statistical models. The core idea of the paper is that such theoretical notions can be spelt out in terms of priors over statistical models, and that such priors can themselves be assigned probabilities. The discussion substantiates the claim that the use of theoretical notions may offer specific empirical advantages. Moreover, I argue that this use of theoretical notions explicates a particular kind of abductive inference. The paper thus contributes to the discussion over Bayesian models of abductive inference.     

Data In Search Of A Principle: A Review Of Relational Frame Theory: A Post-Skinnerian Count Of Human Language And Cognition.

Responding to derived relations among stimuli and events is the subject of an accelerating research program that represents one of the major behavior analytic approaches to complex behavior. Relational Frame Theory: A Post‐Skinnerian Account of Human Language and Cognition (Hayes, Barnes‐Holmes, & Roche, 2001) offers a conceptual framework for this work and explores its implications for verbal behavior and a variety of other domains of complex human behavior. The authors dismiss Skinner's interpretation of verbal behavior as unproductive and conceptually flawed and suggest a new definition and a new paradigm for the investigation of verbal phenomena. I found the empirical phenomena important but the conceptual discussion incomplete. A new principle of behavior is promised, but critical features of this principle are not offered. In the absence of an explicit principle, the theory itself is difficult to evaluate. Counterexamples suggest a role for mediating behavior, perhaps covert, thus raising the question whether a new principle is needed at all. The performance of subjects in relational frame experiments may be a mosaic of elementary behavioral units, some of which are verbal. If so, verbal behavior underlies relational behavior; it is not defined by it. I defend Skinner's definition of verbal behavior and argue that an account of relational behavior must be integrated with Skinner's analysis; it will not replace it.
