‘“Navvy” import alions [sic]’: the schooling of navvy children in the Midlands in the 1890s     

Bryan John Ayres 《History of education》2017,46(4):419-435

The children of navvies were subject to the vagaries of an itinerant lifestyle, and during the latter years of the nineteenth century this invariably affected their relationship with an educational system that mandated compulsory attendance. Based primarily on school records, this article explores the contrasting ways in which teachers perceived navvy children who were admitted to a number of schools during the construction of one particular railway in the mid-1890s. Perceptions concerning the children’s behaviour, attendance, abilities and educational progress, together with evidence of the treatment they received, are considered in the context of contemporary attitudes towards the navvy community and aspects of the navvy lifestyle. The admission of navvy children also had logistical implications for schools, and these are assessed in terms of the pressures placed upon financial resources and teaching staff. This illustrates the disparity that could exist between small rural schools and larger schools in urban areas.  相似文献   

One-trial excitatory backward conditioning as assessed by conditioned suppression of licking in rats: Concurrent observations of lick suppression and defensive behaviors     

John J. B. Ayres  Christopher Haddad  Melody Albert 《Learning & behavior》1987,15(2):212-217

Twenty-eight male albino rats were given a single 4-sec 1-mA electric-grid-shock unconditioned stimulus (US). In the same session they received two 12-sec conditioned stimuli (CSs). One CS (explicitly unpaired) terminated 180 sec before the US began; the other (backward paired) began immediately after the US terminated. The CSs used were a 1000-Hz 85-dB tone and an 84-dB click; their roles were counterbalanced. Over the next 2 days, each CS was presented for 2 min while the rats drank from a water bottle. The backward-paired CS was found to suppress licking more than the explicitly unpaired CS. This suppression was accompanied by an increase in defensive behavior (freezing and freeze/nod) and by a decrease in other activity. The suppression did not seem to be due to a maintained or enhanced CS-orienting response reflex, nor could it be attributed to an adventitiously reinforced interfering operant. The results support the presumption made in previous reports that the lick suppression evoked by a backward CS reflected one-trial backward excitatory fear conditioning.  相似文献   

Concurrent observations of barpress suppression and freezing: Effects of CS modality and on-line vs. off-line training upon posttrial behavior     

John J. B. Ayres  Howard Axelrod  Elizabeth Mercker  Fran Muchnik  Michael Vigorito 《Learning & behavior》1985,13(1):44-50

In a conditioned suppression study with rats, CS modality (light vs. noise) and type of conditioning (on-line vs. off-line training) were manipulated. All rats were then tested on-line with only half the test trials reinforced. Some results and conclusions were as follows: (1) During initial training, suppression following reinforced noise trials was moderately strong at first but weakened over days; for the light, it was weak from the start. It was suggested that this strong influence of CS modality might complicate interpretations of posttrial suppression as a measure of US effectiveness. (2) During testing, posttrial suppression and freezing were greater following non-reinforced trials than following reinforced trials (US-omission effect), and this effect was stronger for noise than for light. Since noise also produced more freezing than light, this result favors the hypothesis that the US-omission effect is due to persistent CS-elicited freezing that is un-disrupted by a shock US. (3) Although noise produced more freezing, both noise and light produced similar barpress suppression. This result is consistent with the suggestion that noise and light acquire equal associative strength but elicit different defensive behaviors.  相似文献   

The movement of the trunk and breast during front crawl and breaststroke swimming     

Chris Mills  Mitch Lomax  Bessie Ayres  Joanna Scurr 《Journal of sports sciences》2015,33(4):427-436

Breast displacement has been investigated in various activities to inform bra design, with the goal of minimising movement; however, breast motion during swimming has yet to be considered. The aim was to investigate trunk and breast kinematics whilst wearing varying levels of breast support during two swimming strokes. Six larger-breasted females swam front crawl and breaststroke (in a swimming flume), in three breast support conditions while three video cameras recorded the motion of the trunk and right breast. Trunk and relative breast kinematics were calculated. Greater breast displacement occurred mediolaterally in the swimsuit condition (7.8, s = 1.5 cm) during front crawl and superioinferiorly in the bare-breasted condition (3.7, s = 1.6 cm) during breaststroke, with the sports bra significantly reducing breast displacements. During front crawl, the greatest trunk roll occurred in the sports bra condition (43.1, s = 8.3°) and during breaststroke greater trunk extension occurred in the swimsuit condition (55.4, s = 5.0°); however, no differences were found in trunk kinematics between the three breast support conditions. Results suggest that the swimsuit was ineffective as a means of additional support for larger-breasted women during swimming; incorporating design features of sports bras into swimsuits may improve the breast support provided.  相似文献   

One-trial context fear conditioning with immediate shock: The roles of transport and contextual cues     

Rick A. Bevins  Anthony S. Rauhut  Janice E. Mcphee  John J. B. Ayres 《Learning & behavior》2000,28(2):162-171

In three experiments, using a total of 120 albino rats, we assessed whether transportation cues might evoke some of the freezing (i.e., defensive immobility) that we see in a context on a day following a footshock given immediately after placement in that context. The results suggested that immediate shock could directly condition strong fear to both simulated and actual transport cues. Although conditioning to transport cues explains some of the freezing that is seen on the test day, it does not explain all of it. We also found evidence that some of the freezing is due to conditioning to permanent features of the context in which the immediate shock is given. The results support a role for transport cues in theories of context conditioning and argue against shock-processing accounts of the conditioning deficit that results from immediate shock.  相似文献

Measuring patients' communication apprehension about interacting with physicians: Instrument development     

Joe Ayres  Noelle Colby‐Rotell  Paul Mark Wadleigh  Tim Hopf 《Communication Research Reports》2013,30(1):86-93

The purpose of these studies was to develop an instrument to measure patients' perceived communication apprehension in patient/physician interactions. In the first stydy, a five item Patients' Report of Communication Apprehension with Physicians (PRCAP) was developed. The scale appears to be a reliable, unidimensional scale which shows a moderate positive correlation with the Personal Report of Communication Apprehension (PRCA), a moderate negative correlation with willingness to communicate (WTC), and a moderate negative correlation with self‐perceived communication competence (SPCC). In the second study, designed to assess the predictive validity of the PRCAP, those who scored one standard deviation above the mean on the PRCAP reported being less satisfied with their interactions with physicians than those who scored one standard deviation below the mean on the PRCAP. It appears the PRCAP is a reliable and valid instrument that can be employed to pursue issues involving the role of CA in patient/physician interactions.  相似文献   

Two empirical tests of a videotape designed to reduce public speaking anxiety     

Joe Ayres  Frances E. Ayres  Alan L. Baker  Noelle Colby  Camille De Blasi  Debbie Dimke 《Journal of Applied Communication Research》2013,41(2):132-147

These studies were designed to determine: 1) if a videotape could be used to help people cope with public speaking anxiety; 2) how this videotape compared with other interventions; 3) whether the video could be used on a self‐help basis; and 4) whether the video would be effective over time. These issues were addressed in two separate studies. These studies indicated that the videotape reduced self‐reported levels of trait CA, state CA, and negative thinking. The first study linked the videotape to reduced rigidity while the second linked the videotape to reduced agitation. The second study also found trait CA to be reduced over time. Meta‐analysis was used to compare these data with other interventions. That analysis revealed this videotape was generally more effective than other interventions in reducing trait CA in study one. The videotape was found to reduce state CA and negative thinking more than other interventions in study two. These and other results are discussed at the conclusion of these studies.  相似文献   

Interdisciplinary Perspectives Inspiring a New Generation of Cognitive Load Research     

Paul Ayres  Fred Paas 《Educational Psychology Review》2009,21(1):1-9

This special issue consists of six theoretical papers and an introduction. Each paper describes a current advance to the applications and focus of cognitive load theory (CLT). Four of the papers use an interdisciplinary approach outside of educational psychology by combining CLT with elements of evolutionary biology, mirror neuron research, cognitive brain science, and the philosophy of science. The remaining two papers use an intradisciplinary approach within educational psychology by applying CLT to self-regulation and heuristic learning. This paper introduces CLT, overviews each contribution, and summarizes the main themes.  相似文献   

A test of two methods for extinguishing Pavlovian conditioned inhibition     

Elizabeth S. Witcher  John J. B. Ayres 《Learning & behavior》1984,12(2):149-156

Two experiments were performed using rats in a conditioned suppression procedure to test two different methods for extinguishing Pavlovian conditioned inhibition. In both experiments, a target stimulus, X, was made inhibitory by giving discrimination training of the form A+ AX?. Then, in Experiment 1, an attempt was made to extinguish the inhibition conditioned to X by presenting nonreinforced occurrences of X, of AX, and of A. Testing for conditioned inhibition took the form B+ BX?. It was found that the extinction procedure did not weaken the inhibitory properties of X. Experiment 2 attempted to extinguish the inhibition conditioned to X by presenting X randomly and independently of the reinforcer, electric grid shock. This procedure appeared to weaken inhibition quickly and permanently.  相似文献
