Age-of-acquisition effects in delayed picture-naming tasks

We report two experiments that explored the linguistic locus of age-of-acquisition effects in picture naming by using a delayed naming task that involved only a low proportion of trials (25 %) while, for the large majority of the trials (75 %), participants performed another task—that is, the prevalent task. The prevalent tasks were semantic categorization in Experiment 1a and grammatical-gender decision in Experiments 1b and 2. In Experiment 1a, in which participants were biased to retrieve semantic information in order to perform the semantic categorization task, delayed naming times were affected by age of acquisition, reflecting a postsemantic locus of the effect. In Experiments 1b and 2, in which participants were biased to retrieve lexical information in order to perform the grammatical gender decision task, there was also an age-of-acquisition effect. These results suggest that part of the age-of-acquisition effect in picture naming occurs at the level at which the phonological properties of words are retrieved.     

Developmental changes in probabilistic reasoning: The role of cognitive capacity,instructions, thinking styles,and relevant knowledge

In three experiments we explored developmental changes in probabilistic reasoning, taking into account the effects of cognitive capacity, thinking styles, and instructions. Normative responding increased with grade levels and cognitive capacity in all experiments, and it showed a negative relationship with superstitious thinking. The effect of instructions (in Experiments 2 and 3) was moderated by level of education and cognitive capacity. Specifically, only higher-grade students with higher cognitive capacity benefited from instructions to reason on the basis of logic. The implications of these findings for research on the development of probabilistic reasoning are also discussed.     

Spinoza on Causation and Power

The purpose of this paper is to argue that, for Spinoza, causation is a more fundamental relation than conceptual connection, and that, in fact, it explains conceptual connection. I will firstly offer a criticism of Michael Della Rocca's 2008 claims that, for Spinoza, causal relations are identical to relations of conceptual dependence and that existence is identical to conceivability. Secondly, I will argue that, for Spinoza, causation is more fundamental than conceptual dependence, offering textual evidence from both Treatise on the Emendation of the Intellect and Ethics. In particular, I will offer an interpretation of the attributes as first and foremost causal activities, or powers: this interpretation has the advantage to clarify the role of 1D6 as a “genetic definition.”     

Alarm Signals and Prompts to Eliminate Large Urinary Accidents in a Woman with Multiple Disabilities

Urine-triggered alarm signals and prompts were used to help a woman with multiple disabilities halt wetting episodes and walk to the toilet (thus avoiding large urinary accidents). Data indicated that the woman had a mean frequency of 1 large accident nearly every 2 days during the baseline phases and every 20 days during the intervention phases. During the latter phases, large accidents were replaced by small accidents (i.e. only a disposable tissue inside the underwear was wet), which did not cause environmental disruptions and did not require changes of clothes. Implications of the findings are discussed.     

Promoting Mild Physical Exercise in a Person with Profound Multiple Disabilities

Prompt/orientation cues delivered through an automatic system were combined with one or two reinforcement events in order to promote mild physical exercise independent of staff in a man with profound multiple disabilities. The exercise sessions were gradually extended to 60 minutes. Data indicated that the man achieved high levels of exercise engagement. There were minimal differences in terms of engagement between sessions with one reinforcement event and those with two reinforcement events. Yet, in the latter sessions, the man had higher levels of positive mood. Implications of the findings are discussed.     

An Interrater Reliability Study of Rorschach Performance Assessment System (R–PAS) Raw and Complexity-Adjusted Scores

Recently, the Rorschach Performance Assessment System (R–PAS; Meyer, Viglione, Mihura, Erard, &; Erdberg, 2011 Meyer, G. J., Viglione, D. J., Mihura, J. L., Erard, R. E., &; Erdberg, P. (2011). A manual for the Rorschach Performance Assessment System. Toledo, OH: R–PAS. [Google Scholar]) was introduced to overcome some possible limitations of the Comprehensive System (CS; Exner, 2003 Exner, J. E. (2003). The Rorschach: A comprehensive system. Vol. 1: Basic foundations and principles of interpretation (4th ed.). Hoboken, NJ: Wiley. [Google Scholar]) while continuing its efforts to link Rorschach inferences to their evidence base. An important, technical modification to the scoring system is that R–PAS interpretations are based on both standard scores and complexity-adjusted scores. Two previous U.S. studies reported good to excellent interrater reliability (IRR) for the great majority of R–PAS variables; however, IRR of complexity-adjusted scores has never been investigated. Furthermore, no studies have yet investigated R–PAS IRR in Europe. To extend this literature, we examined R–PAS IRR of Page 1 and Page 2 raw and complexity-adjusted scores with 112 Italian Rorschach protocols. We collected a large sample of both clinical and nonclinical Rorschach protocols, each of which was coded separately by 2 independent raters. Results demonstrated a mean intraclass correlation of .78 (SD = .14) for raw scores and.74 (SD = .14) for complexity-adjusted scores. Overall, for both raw and complexity-adjusted values, most of the variables were characterized by good to excellent IRR.
