Reliability and Validity of the Current Anxiety Level Measure

Professionals interested in assessing state anxiety (in the moment) levels before and after brief activity-based treatments would find limited evidence-based assessments. The purpose of this study was to develop and test the current anxiety level measure, a free, valid, and reliable state anxiety assessment. To establish concurrent validity, the current anxiety level measure was administered (n?=?98) alongside the State-Trait Anxiety Inventory. Results found a strong relationship (r?=?.904, p?r?=?.702, p?n?=?102). Both samples showed the current anxiety level measure to be reliable and valid.     

BIOLOGY TEACHERS’ CONCEPTIONS ABOUT THE ORIGIN OF LIFE IN BRAZIL,ARGENTINA, AND URUGUAY: A COMPARATIVE STUDY

Teachers’ conceptions about the origin of life in three Latin American countries with contrasting levels of secularism were analyzed: Argentina (Catholic constitution), Brazil (formally secular but not in practice), and Uruguay (consolidated secularism). A European survey questionnaire was used and the interpretation of the results drew on Barbour's four categories concerning the relationships of science and religion. A large majority of Argentinian and Uruguayan teachers were clearly evolutionist, even when believing in God (Independence or Dialogue category), with no difference between Argentina and Uruguay. The majority of Brazilian teachers assumed a religious position about the origin of life, being creationist (Conflict or Independence categories) or evolutionary creationist (Dialogue or Integration categories). Differences of Brazilian teachers’ conceptions may result from the higher percentage of evangelicals and lower proportion of agnostics/atheists. Brazilian Catholic teachers were more creationist than their Catholic colleagues in Argentina and Uruguay. Distinct patterns were found, but further research is needed to understand possible classroom impacts.     

The tuning-fork model of human social cognition: a critique

The tuning-fork model of human social cognition, based on the discovery of mirror neurons (MNs) in the ventral premotor cortex of monkeys, involves the four following assumptions: (1) mirroring processes are processes of resonance or simulation. (2) They can be motor or non-motor. (3) Processes of motor mirroring (or action-mirroring), exemplified by the activity of MNs, constitute instances of third-person mindreading, whereby an observer represents the agent's intention. (4) Non-motor mirroring processes enable humans to represent others' emotions. After questioning all four assumptions, I point out that MNs in an observer's brain could not synchronically resonate with MNs in an agent's brain unless they discharged in a single brain in two distinct tasks at different times. Finally, I sketch a conceptualist alternative to the resonance model according to which a brain mechanism active in both the execution and the perception of e.g., the act of grasping is the neural basis of the concept of e.g., grasping.     

Lengthening the duration of response execution does not modulate blindness to action-compatible stimuli.

Action-compatible blindness refers to the finding that target stimuli are perceived less frequently if they are presented during the planning or execution of a compatible action (e.g., a left arrow presented during a left manual key press) than during an incompatible action (Müsseler & Hommel, 1997 a, b). We investigated the effect of lengthening the response execution phase in the action-compatible blindness paradigm by requiring subjects to tap a response key once or three times on the assumption that tapping three times would increase the duration of the execution phase of the response. Prior research (e.g., Stevanovski, Oriet, & Jolicoeur, 2002; Wühr & Müsseler, 2001) has shown that larger blindness effects are observed for targets presented during the execution phase of a response than after the response has been made. We investigated whether a larger blindness effect would be observed in the three-tap condition than in the one-tap condition, or whether lengthening the duration of the response would extend the time course of the blindness effect. Neither of these possibilities was supported by the data irrespective of whether the number of taps to be made was blocked or mixed within a block of trials. The results are discussed in terms of current accounts of action-compatible blindness and the possible cognitive differences between making a single response and repeating a response.     

Development of children's mental representations: effects of age, sex, and school experience

In the present study mental representations in drawings by 158 young children, ages 2 1/2 to 6 yr. old were analysed. The aim was to investigate whether the accuracy of mental representations increased with age and how this development progressed. Also tested were whether the inferred mental representations differed for boys and girls and whether preschool experience affected the drawings. As expected, mental representation increased in complexity with age as measured by Goodenough's score, and girls' mental representations (drawings) were significantly more elaborate than boys. Moreover, attending school early seemed to affect mental representations of the 3-yr.-olds but not the 4-yr.-olds. Results are discussed in terms of internal and external factors in mental representation in drawing a man.     

Shades of disengagement: high school dropouts speak out

The purpose of this study was to describe how dropouts navigate their educational journeys. Eighty dropouts participated to individual interviews which were recorded and transcribed. The data analysis yielded three broad categories in answering the research question. Setting the stage in the family and the school, the dropouts described their teetering between in and out of school contexts and proceeded to explain how they ended their educational journey. For 20 dropouts, family turmoil represented a pervasive force negatively influencing their schooling. For 24 dropouts, problems in school set the stage for dropping out. Teetering represented juggling strategies to prolongand to sabotage the journey, while the end of the journey occurred as a result of a pivotal moment (48%) or a gradual fade out (52%) from the school context.
