The Impact of CACREP Accreditation: A Multiway Frequency Analysis of Ethics Violations and Sanctions

The impact of CACREP accreditation on counselor competency has received little empirical investigation. Differences in the frequency and type of ethical misconduct between graduates of CACREP‐accredited and non‐CACREP‐accredited counselor education programs were investigated. Results of a multiway frequency analysis indicated that fully licensed graduates of CACREP‐accredited programs were sanctioned for ethical misconduct significantly less frequently than were graduates of non‐CACREP‐accredited programs. Additionally, the accreditation factor was among the highest‐ranking parameter estimates of expected cell frequencies.     

Learning about Frequency on the Fly: Recent Experience Changes Strategies Regarding Linguistic Frequency in Recognition Memory

In the present study, the author examines whether participants can adjust recognition response strategies to account for the effects of linguistic frequency. Experiment 1 used a counterfeit-list technique to replicate findings that indicate that participants exhibit a bias toward choosing high-frequency lures. Experiment 2 demonstrates that when participants are exposed to a training phase that includes an opportunity to recognize high- and low-frequency words, participants no longer demonstrate a significant bias toward choosing high-frequency items on the counterfeit list task. Experiments 3 and 4 examine how participants learn to adjust for linguistic frequency by manipulating the information available during training. The results demonstrate that participants use information from the training phase indicating that high word frequency is a good cue to oldness to guide their memory decisions during the counterfeit list task, but do not use training phase information indicating that low frequency is the best cue to oldness in a similar fashion.     

Compressing movement information via principal components analysis (PCA): Contrasting outcomes from the time and frequency domains

PCA has become an increasingly used analysis technique in the movement domain to reveal patterns in data of various kinds (e.g., kinematics, kinetics, EEG, EMG) and to compress the dimension of the multivariate data set recorded. It appears that virtually all movement related PCA analyses have, however, been conducted in the time domain (PCA_t). This standard approach can be biased when there are lead-lag (phase-related) properties to the multivariate time series data. Here we show through theoretical derivation and analysis of simulated and experimental postural kinematics data sets that PCA_t and, PCA in the frequency domain (PCA_f), can lead to contrasting determinations of the dimension of a data set, with the tendency of PCA_t to overestimate the number of components. PCA_f also provides the possibility of obtaining amplitude and phase-difference spectra for each principal component that are uniquely suitable to reveal control mechanisms of the system. The bias in the PCA_t estimate of the number of components can have significant implications for the veracity of the interpretations drawn in regard to the dynamical degrees of freedom of the perceptual-motor system.     

Separating value from selection frequency in rapid reaching biases to visual targets

Stimuli associated with positive rewards in one task often receive preferential processing in a subsequent task, even when those associations are no longer relevant. Here we use a rapid reaching task to investigate these biases. In Experiment 1 we first replicated the learning procedure of Raymond and O'Brien (2009), for a set of arbitrary shapes that varied in value (positive, negative) and probability (20%, 80%). In a subsequent task, participants rapidly reached toward one of two shapes, except now the previously learned associations were irrelevant. As in the previous studies, we found significant reach biases toward shapes previously associated with a high probable, positive outcome. Unexpectedly, we also found a bias toward shapes previously associated with a low probable, negative outcome. Closer inspection of the learning task revealed a potential second factor that might account for these results; since a low probable negative shape was always paired with a high probable negative shape, it was selected with disproportionate frequency. To assess how selection frequency and reward value might both contribute to reaching biases we performed a second experiment. The results of this experiment at a group level replicated the reach-bias toward positively rewarding stimuli, but also revealed a separate bias toward stimuli that had been more frequently selected. At the level of individual participants, we observed a variety of preference profiles, with some participants biased primarily by reward value, others by frequency, and a few actually biased away from both highly rewarding and high frequency targets. These findings highlight that: (1) rapid reaching provides a sensitive readout of preferential processing; (2) target reward value and target selection frequency are separate sources of bias; and (3) group-level analyses in complex decision-making tasks can obscure important and varied individual differences in preference profiles.     

Articulatory coding and phonological judgements on written words and pictures: The role of the phonological output buffer

Abstract

The ability of Italian subjects to make phonological judgements was investigated in three experiments. The judgements comprised initial sound similarity and stress assignment on pain of both written words and pictures. Stress assignment on both words and pictures as well as initial sound similarity on pictures required the activation of phonological lexical representations, but this was not necessarily the case for initial sound similarity judgements on word pairs. The first study assessed the effects of concurrent articulatory suppression on the judgements. Experiment 2 used a concomitant task (chewing), which shares with suppression the use of articulatory components but does not involve speech programming and production. The third experiment investigated the effects of unattended speech on the phonological judgements. The results of these three experiments showed that articulatory suppression had a significant disrupting effect on accuracy in all four conditions, while neither articulatory non-speech (chewing) or unattended auditory speech had any effect on the subjects' performance. The results suggest that these phonological judgements involve the operation of an articulatory speech output component, which is not implemented peripherally and does not require the involvement of a non-articulatory input system.     

About the locus of the distractor frequency effect: Evidence from the production of clitic pronouns

In this study, we report results from two experiments in which pictures were shown with superimposed distractors that varied along two dimensions: frequency (high vs. low) and semantic relation with respect to the picture (related vs. unrelated). In one condition of Experiment 1, participants named pictures with a noun utterance; in the other condition of Experiment 1 and in Experiment 2 participants named pictures with a pronominal utterance. Low frequency distractor words produced greater interference with respect to high frequency words in noun production, but not in pronoun production. Critically, a semantic interference effect, greater interference in the semantically related than unrelated condition, was reported in both experiments, suggesting that distractor words were equally processed in both noun and pronoun conditions. These results are discussed in the context of current models of picture–word interference.     

Word frequency and root-morpheme frequency effects on processing of Korean particle-suffixed words

Two experiments investigated the roles of the frequency of the root morpheme and the frequency of the whole word for a particular type of suffixed word in Korean in which the suffixed word can be thought of as a phrase (e.g., grandson-with). In both experiments, sentence frames were constructed so that they could have one of two target words that varied on frequency characteristics in the same location in the sentence. In Experiment 1, the frequency of the root morpheme was varied with the frequency of the word controlled, and in Experiment 2, the frequency of the word was varied with the frequency of the root morpheme controlled. Word frequency had a significant effect on fixation times, whereas root morpheme frequency did not. The results were surprising as native Korean speakers view the root morpheme as the “word” (analogous to how English readers would view a noun followed by a prepositional phrase).     

The Effects of Frequency of Social Interaction and Relationship Closeness on Reward Allocation

In this study of how the frequency of interaction affects decisions on reward allocation, 320 Chinese adults were randomly assigned to 8 conditions and instructed to read a scenario describing 2 co-workers completing a task and obtaining a bonus. The 8 conditions differed in the type of relationships, the frequency of past interaction between co-workers, and the possibility of future interaction. Each participant was instructed to act as the allocator and to hypothetically allocate a monetary reward to the co-worker. The results indicated that both past interaction and future interaction between the co-workers significantly influenced the allocation decision. These results also suggested that the frequency of 2 individuals' past interaction can be predictive of the closeness of their relationship.     

Relation of self-talk frequency to loneliness,need to belong,and health in German adults

This study examined whether individuals with a high need to belong and feelings of loneliness tend to compensate for a lack of social contact by self-talk and whether self-talk prevents negative consequences on their physical and mental health. The sample consisted of 559 adults drawn from the German Sozioland Panel Project. The results of SEM analyses revealed evidence for significant relations of the need to belong and loneliness with the frequency of self-talk. Moreover, the need to belong and loneliness were significantly related to mental and physical health, but loneliness was shown to be more important for the prediction of both health outcomes. Results of moderator analyses indicate that self-talk might be a risk factor for an increased negative correlation between loneliness and mental health. Self-talk, which is supposed to be related to self-awareness, might reinforce the subjective feeling of loneliness and hence have a negative impact on psychological well-being.
