Colonised minds and community psychology in the academy: Collaborative autoethnographic reflections.

We reflect on decolonization and in particular the process of decolonizing our own minds. We discuss the need for radical decolonization of psychology and for critique of community psychology's relationship to both psychology and the Academy, noting ways in which community psychology itself becomes appropriated for the colonizing project of the Academy. Using collaborative autoethnography (CAE), a method that involves "collaborative poetics," which chimes with the emphasis on participatory research in community psychology and the decolonialist emphasis on rescuing repressed epistemologies, we review our own careers and identify ways in which our values have been compromised and our work assimilated into wider colonizing and oppressive practices that sustain the modern university. We conclude that community psychology can only decolonize if it is positioned in an agonistic relationship to mainstream psychology and exists as a radical, explicitly political, and ethical practice outside the Academy. The message of the decolonization and disalienation movements is that the biggest barrier to our effectiveness, and to social justice, is the fascism of our minds. Succumbing to the power and privilege embedded in the Academy and the oppressive and colonizing practices that sustain it conflicts with community psychology's purported values.

Whole-Body Change-of-Direction Task Execution Asymmetries After Anterior Cruciate Ligament Reconstruction.

Cutting maneuvers can be executed at a range of angles and speeds, and these whole-body task descriptors are closely associated with lower-limb mechanical loading. Asymmetries in angle and speed when changing direction off the operated and nonoperated limbs after anterior cruciate ligament reconstruction may therefore influence the interpretation of interlimb differences in joint-level biomechanical parameters. The authors hypothesized that athletes would reduce center-of-mass heading angle deflection and body rotation during the change-of-direction stance phase when cutting from the operated limb, and would compensate for this by orienting their center-of-mass trajectory more toward the new intended direction of travel prior to touchdown. A total of 144 male athletes 8 to 10 months after anterior cruciate ligament reconstruction performed a maximum-effort sidestep cutting maneuver while kinematic, kinetic, and ground reaction force data were recorded. Peak ground reaction force and knee joint moments were lower when cutting from the operated limb. Center-of-mass heading angle deflection during stance phase was reduced for cuts performed from the operated limb and was negatively correlated with heading angle at touchdown. Between-limb differences in body orientation and horizontal velocity at touchdown were also observed. These systematic asymmetries in cut execution may require consideration when interpreting joint-level interlimb asymmetries after anterior cruciate ligament reconstruction and are suggestive of the use of anticipatory control to co-optimize task achievement and mechanical loading.

How fluent is the fluent speech of people who stutter? A new approach to measuring kinematics with ultrasound.

We present a new approach to the investigation of dynamic ultrasound tongue imaging (UTI) data, applied here to analyse the subtle aspects of the fluency of people who stutter (PWS). Fluent productions of CV syllables (C = /k/; V = /ɑ, i, ə/) from three PWS and three control speakers (PNS) were analysed for duration and peak velocity relative to articulatory movement towards (onset) and away from (offset) the consonantal closure. The objective was to apply a replicable methodology for kinematic investigation to speech of PWS in order to test Wingate's Fault-Line hypothesis. As was hypothesised, results show comparable onset behaviours for both groups. Regarding offsets, groups differ in peak velocity. Results suggest that PWS do not struggle initiating consonantal closure (onset). In transition from consonantal closure into the vowel, however, groups appear to employ different strategies expressed in increased variation (PNS) versus decreased mean peak velocity (PWS).

Articulatory imaging implicates prediction during spoken language comprehension.

It has been suggested that the activation of speech-motor areas during speech comprehension may, in part, reflect the involvement of the speech production system in synthesizing upcoming material at an articulatorily specified level. In this study, we explored that suggestion through the use of articulatory imaging. We investigated whether, and how, predictions that emerge during speech comprehension influence articulatory realizations during picture naming. We elicited predictions by auditorily presenting high-cloze sentence stems to participants (e.g., When we want water we just turn on the . . .). Participants named a picture immediately following each sentence-stem presentation. The pictures either matched (e.g., TAP) or mismatched (e.g., CAP) the high-cloze sentence-stem target. Throughout each trial, participants' speech-motor movements were recorded via dynamic ultrasound imaging. This allowed us to compare articulations in the match and mismatch conditions to each other and to a control condition (simple picture naming). Articulations in the mismatch condition differed more from the control condition than did those in the match condition. This difference was reflected in a second analysis that showed greater frame-by-frame change in articulator positions for the mismatch than for the match condition around 300-500 ms before the onset of the picture name. Our findings indicate that comprehension-elicited prediction influences speech-motor production, suggesting that the speech production system is implicated in the representation of such predictions.

Effects in production of word pre-activation during listening: are listener-generated predictions specified at a speech-sound level?

It has been demonstrated that listener-generated predictions of upcoming material can be specified to a phonological level, such that a specific word onset is anticipated (e.g., DeLong, Urbach, & Kutas, Nature Neuroscience, 8, 1117-1121, 2005). In the present study, we investigated whether such word-form-specific predictions impact picture-naming latencies in a manner similar to that observed when a distractor word is actually presented. Participants were auditorily presented with high-cloze sentence stems, in order to elicit word-form predictions. The pictures for naming were presented immediately following the sentence stem. We systematically manipulated the phonological relationship between the predicted word and the picture name. Across three experiments, naming was facilitated when the picture name fully matched the predicted word. However, naming was neither facilitated nor inhibited when the picture name overlapped phonologically with the predicted word. This finding is in contrast to the known effects of phonological overlap when a distractor word is heard or read. Our findings suggest that words that are internally listener-generated (predicted) during comprehension are not robustly specified at a speech-sound (phonological) level.

Perfectionism and stuttering: Findings of an online survey.

PURPOSE: Using a multi-dimensional measure of perfectionism: the Frost Multi-dimensional Perfectionism Scale (FMPS: Frost, Marten, Lahart, & Rosenblate, 1990), this study investigates: (a) whether adults who stutter (AWS) display more perfectionistic attitudes and beliefs than those who do not stutter, and (b) whether, in AWS, more perfectionistic attitudes and beliefs are associated with greater self-reported difficulty communicating verbally and speaking fluently. METHOD: In the first analysis, FMPS responses from 81 AWS and 81 matched, normally-fluent controls were analyzed using logistic regression to investigate the relative contributions of four FMPS perfectionism-subscale self-ratings to the likelihood of being in the AWS group. In the subsequent analyses, data from the 81 AWS were analyzed using linear multiple regression to determine which FMPS subscale self-ratings best predicted their Communication-Difficulty and Fluency-Difficulty scores. RESULTS: Both the likelihood of being a member of the AWS group, and also the magnitude of the AWS group's Communication-Difficulty and Fluency-Difficulty scores, were positively part-correlated to respondents' Concern over Mistakes-Doubts about Actions (CMD) subscale self-ratings but negatively part-correlated to their Personal Standards (PS) subscale self-ratings. CONCLUSIONS: The FMPS profiles of respondents who stutter suggest that, as a group, they are not abnormally perfectionistic overall, but may be (or perceive themselves to be) abnormally error-prone. Also, AWS who are more concerned about their errors and uncertain of their actions experience more difficulty communicating verbally and speaking fluently. EDUCATIONAL OBJECTIVES: After reading this article, participants will be able to: (a) describe the findings of previous research investigating the role of perfectionism in stuttering and psychopathologies; (b) discuss why a multidimensional assessment of perfectionism is important in relation to stuttering; (c) discuss ways in which data from perfectionism assessments can contribute to the planning of therapy for adults who stutter.
