Building pathways to academic success: a practice report

Students attending university for the first time come with a range of expectations, experiences and skills. For many these prior experiences are less than optimal for achieving academic success. This paper evaluates the academic outcomes across three cohorts of a five day enabling program offered to commencing students in the week prior to their formal university orientation program. The demographics of this sample (n=965) are such that over 50% come from low socio-economic backgrounds, about 50% are first in family to attend university, 50% are mature age students and over 50% have university entrance scores in the lower ranges of academic ability. Those who entered university with an OP1 score of 15 or less and completed the program were less likely to fail and achieved higher GPAs at the end of their first semester of studies than those who did not complete the enabling program

Order recall in verbal short-term memory: The role of semantic networks

In their recent article, Acheson, MacDonald, and Postle (Journal of Experimental Psychology: Learning, Memory, and Cognition 37:44-59, 2011) made an important but controversial suggestion: They hypothesized that (a) semantic information has an effect on order information in short-term memory (STM) and (b) order recall in STM is based on the level of activation of items within the relevant lexico-semantic long-term memory (LTM) network. However, verbal STM research has typically led to the conclusion that factors such as semantic category have a large effect on the number of correctly recalled items, but little or no impact on order recall (Poirier & Saint-Aubin, Quarterly Journal of Experimental Psychology 48A:384-404, 1995; Saint-Aubin, Ouellette, & Poirier, Psychonomic Bulletin & Review 12:171-177, 2005; Tse, Memory 17:874-891, 2009). Moreover, most formal models of short-term order memory currently suggest a separate mechanism for order coding-that is, one that is separate from item representation and not associated with LTM lexico-semantic networks. Both of the experiments reported here tested the predictions that we derived from Acheson et al. The findings show that, as predicted, manipulations aiming to affect the activation of item representations significantly impacted order memory

Factor analysis of a questionnaire used for developing an operational philosophy for habilitation facilities

In order to assist Activity Therapy Centre staff examine their attitudes towards current habilitataion practices, and, to the principles of normalization, a questionnaire seeking this information was devised as a preliminary exercise to a workshop held to discuss and develop an operational philosophy for individual centres. This paper describes the questionnaire and examines its factor structure. A series of Alpha Factor Analyses suggested that the questionnaire is characterized by two factors. Fifteen of the eighteen value statements covered by the questionnaire load on the first factor, accounting for seventy percent of the common variance, on average. This factor seems to be a general habituation factor. The remaining three areas form a second factor, accounting for fourteen percent of the common variance, on average. This second factor is a nonhabilitation factor, but remains important for the formulation of an operational philosophy

Does neighbourhood size really cause the word length effect?

In short-term serial recall, it is well-known that short words are remembered better than long words. This word length effect has been the cornerstone of the working memory model and a benchmark effect that all models of immediate memory should account for. Currently, there is no consensus as to what determines the word length effect. Jalbert and colleagues (Jalbert, Neath, Bireta, & Surprenant, 2011a; Jalbert, Neath, & Surprenant, 2011b) suggested that neighborhood size is one causal factor. In six experiments we systematically examined their suggestion. In Experiment 1, with an immediate serial recall task, multiple word lengths, and a large pool of words controlled for neighborhood size, the typical word length effect was present. In Experiments 2 and 3, with an order reconstruction task and words with either many or few neighbors, we observed the typical word length effect. In Experiment 4 we tested the hypothesis that the previous abolition of the word length effect when neighborhood size was controlled was due to a confounded factor: frequency of orthographic structure. As predicted, we reversed the word length effect when using short words with less frequent orthographic structures than the long words, as was done in both of Jalbert et al.’s studies. In Experiments 5 and 6, we again observed the typical word length effect, even if we controlled for neighborhood size and frequency of orthographic structure. Overall, the results were not consistent with the predictions of Jalbert et al. and clearly showed a large and reliable word length effect after controlling for neighborhood size
