Value learning modulates goal-directed actions

With experience, particular objects can predict good or bad outcomes. This alters our perceptual response to them: Reliable predictors of salient outcomes are recognized faster and better than unreliable predictors, regardless of the value (gain, loss) of the outcome they predict. When attentional resources are constrained, learned value associations matter, causing recognition of gain-associated objects to be spared. Here, we ask how learned predictiveness and value change the way we interact with potentially rewarding objects. After associating virtual objects (drinking flutes) with monetary gains or losses, reaching for and grasping corresponding real objects depended on the object's learned value. Action was faster when directed at objects that previously predicted outcomes more rather than less consistently, regardless of value. Conversely, reaches were more direct for gain- than for loss-associated objects, regardless of their predictiveness. Action monitoring thus reveals how value learning components become accessible during action.     

A perception-action strategy for hummingbirds

Many human and animal tasks are thought to be controlled with the tau informational variable. It is widely accepted that controlling the rate of change of tau (tau) during decelerative tasks, such as when braking or landing, is one common perceptual control strategy. However, many tasks require accelerating before decelerating to a goal, such as reaching. An advancement of tau theory shows how a single action formula may be used to control the full action unit from initiation to peak velocity, and to rest at the goal, with the same perceptual tau information as before and accounting for the same decelerative kinematics as before. Here, we test the theory against data from high-speed video of a hummingbird flying to its flower feeder. We find that the theory accounts for 97% of the variance in the data, and thus supports it.     

The effects of mindful learning on pro-environmental behavior: A self-expansion perspective

This current article explores the differential effects of mindful learning on pro-environmental behavior from the perspective of self-expansion. A total of 253 participants were recruited for four experiments. In Study 1, the mindful-learning group reported greater levels of pro-environmental behavioral intentions compared to a randomized control. In Study 2, we utilized different learning materials focusing on self, humans, or the biosphere in three sub-experiments. Study 2a manipulated mindsets by a self-related focus and revealed participants in a mindfulness condition had lower pro-environmental behavioral intentions than those in the mindlessness group. Study 2b centered on “humans” and results showed that participants in a mindfulness group reported higher levels of pro-environmental behavioral intentions. Finally, Study 2c induced mindsets with a biospheric focus, showing participants in the mindful-learning condition had greater pro-environmental behavioral intentions. Combined, the studies provide empirical evidence that mindful learning could influence self-reported pro-environmental behavioral intentions both positively and negatively.     

The memorizing effort heuristic in judgments of learning: A developmental perspective

Recent work on adult metacognition indicates that although metacognitive monitoring often guides control operations, sometimes it follows control operations and is based on the feedback from them. Consistent with this view, in self-paced learning, judgments of learning (JOLs) made at the end of each study trial decreased with the amount of time spent studying the item, suggesting that JOLs are based on the memorizing effort heuristic that easily learned items are more likely to be remembered. Study 1 extended investigation to primary school children. Whereas for third to sixth graders (9- to 12-year-olds) JOLs decreased with increasing study time (ST), no such relationship was found for first and second graders (7- and 8-year-olds). For both age groups, however, recall decreased with ST, supporting the validity of the memorizing effort heuristic. Self-reports (Study 2) disclosed the belief that recall should tend to increase with ST. The results bring to the fore the importance of mnemonic cues that shape metacognitive feelings even among primary school children. These cues lie in the very feedback that learners gain on-line from task performance rather than in metacognitive knowledge, and their use may also contribute to increased monitoring accuracy with age.     

A perception-action coupling type of control in long jumping

The authors' goal was to identify the control mechanisms used by long jumpers (N = 6) to precisely position their foot at the board. In addition to the intertrial method usually used in previous research, an original method based on a trial-by-trial analysis was also implemented. If the approach to the board in long jumping encompasses two distinct sequences separated by a key step that marks the initiation of visual control, then a trial-by-trial analysis should reveal those sequences, regardless of the amount of adjustment: The step number at which regulation is initiated should be the same irrespective of the amount of adjustment. If, in contrast, a perception-action coupling mechanism operates, then the step number at which regulation is initiated should be a function of the amount of adjustment: A linear relation between those 2 variables should emerge. The results of the present study are compatible with continuous control mechanisms based on a perception-action coupling.     

A computer-automated laboratory for studying complex perception-action skills

In this paper, we describe a computer-based laboratory for collecting and analyzing real-time performance and eye-movement data by using video game-like tasks. These tasks assess skills that require the integration of varying numbers of perception and action components. Customized hardware and software are described for configuring tasks, collecting data, reconstructing performance, and organizing, editing, and reducing data. General design considerations are emphasized for solving several of the problems encountered in constructing a real-time data collection system. The paper concludes with examples of data that illustrate the system’s usefulness for studying complex perception-action skills.     

The gendered nature of career related learning experiences: A social cognitive career theory perspective

The learning experiences questionnaire (LEQ; Schaub & Tokar, 2005) was used to examine learning experiences as they relate to SCCT (Lent, Brown, & Hackett, 1994) across the Holland (1997) RIASEC typology. In particular, differences in men’s and women’s career related learning experiences were examined. A sample of 319 undergraduates at a public Midwestern university completed an online survey. Gender differences were observed in reported levels of some learning experiences; similar to prior findings for self-efficacy and interests, women reported more learning experiences in the Social domain, and men reported more experiences in the Realistic and Investigative domains. Results also supported that more reported learning experiences in a given domain relate to higher self-efficacy and outcome expectations in that domain.     

The adolescent with a learning disability: a developmental perspective

The psychosocial difficulties that usually accompany learning disabilities are examined from a framework of developmental theory, particularly that of Erik Erikson. The implications of this perspective for treatment of adolescents with learning problems is discussed, and a specific program described.

Evolution and learning: An epistemological perspective

The deep formal and conceptual link existing between artificial life and artificial intelligence can be highlighted using conceptual tools derived by Karl Popper's evolutionary epistemology. Starting from the observation that the structure itself of an organism embodies knowledge about the environment which it is adapted to, it is possible to regard evolution as a learning process. This process is subject to the same rules indicated by Popper for the growth of scientific knowledge: causal conjectures (mutations) and successive refutations (extinction). In the field of machine learning such a paradigm is represented by genetic algorithms that, simulating biological processes, emulate cognitive processes. From a practical viewpoint, that perspective allows to identify the two different kinds of learning considered by artificial intelligence, knowledge acquisition and skill improvement, and to get a different view of the problem of heuristic knowledge in learning systems. From a theoretical point of view, these considerations can shade a new light on an old epistemological problem: why do we live in a learnable world?     

Ethical leadership: A social learning perspective for construct development and testing

Leaders should be a key source of ethical guidance for employees. Yet, little empirical research focuses on an ethical dimension of leadership. We propose social learning theory as a theoretical basis for understanding ethical leadership and offer a constitutive definition of the ethical leadership construct. In seven interlocking studies, we investigate the viability and importance of this construct. We develop and test a new instrument to measure ethical leadership, examine the proposed connections of ethical leadership with other constructs in a nomological network, and demonstrate its predictive validity for important employee outcomes. Specifically, ethical leadership is related to consideration behavior, honesty, trust in the leader, interactional fairness, socialized charismatic leadership (as measured by the idealized influence dimension of transformational leadership), and abusive supervision, but is not subsumed by any of these. Finally, ethical leadership predicts outcomes such as perceived effectiveness of leaders, followers’ job satisfaction and dedication, and their willingness to report problems to management.     

Upper processing stages of the perception-action cycle

The neural substrate for behavioral, cognitive and linguistic actions is hierarchically organized in the cortex of the frontal lobe. In their methodologically impeccable study, Koechlin et al. reveal the neural dynamics of the frontal hierarchy in behavioral action. Progressively higher areas control the performance of actions requiring the integration of progressively more complex and temporally dispersed information. The study substantiates the crucial role of the prefrontal cortex in the temporal organization of behavior.     

A cognitive learning perspective on women becoming expert managers

Despite recent gains, women still face the glass ceiling—an invisible barrier that blocks their entry into top executive positions. Explanations for women's lack of success range from blaming men for discrimination to blaming women themselves. Rather than blaming the people in organizations, it is useful to analyze the task facing women managers. I argue that understanding the inherent difficulties in women's work can provide a new perspective on why women have difficulty in achieving top positions. Recent work in cognitive psychology is helping us learn more about the processes involved in reaching high levels of performance. Using these theories and concepts to analyze the task facing women managers, we can begin to develop new ways to help women develop higher levels of managerial skill.     

Keeping the driver in the loop in conditionally automated driving: A perception-action theory approach

In this paper we investigated if keeping the driver in the perception–action loop during automated driving can improve take-over behavior from conditionally automated driving. To meet this aim, we designed an experiment in which visual exposure (perception) and manual control exposure (action) were manipulated. In a dynamic driving simulator experiment, participants (n = 88) performed a non-driving related task either in a head-up display in the windshield (high visual exposure) or on a head-down display near the gear shift (low visual exposure). While driving, participants were either in an intermittent control-mode with four noncritical take-over situations (high manual control exposure), or in a continuous automation-mode throughout the ride (low manual control exposure). In all conditions, a critical take-over had to be carried out after an approximately 13 min ride. Measurements of take-over behavior showed that only high visual exposure had an effect on hands-on reaction time measurements. Both visual exposure and manual control exposure had small to medium sized main effects on time to system deactivation, the maximum velocity of the steering wheel, and the standard deviation of the steering wheel angle. The combined high visual – and high manual control exposure condition led to 0.55 s faster reaction time and 37% less steering variability in comparison to the worst case low visual – and low manual control exposure condition. Together, results corroborate that maintaining visual exposure and manual control exposure during automated driving can be efficacious and suggest that their positive effects are additive.     

The shape of things to come: Exploring goal-directed prospection

Through the ability to preview the future (i.e., prospection), people can anticipate how best to think, feel and act in just about any setting. But exactly what factors determine the contents of prospection? Extending research on action identification and temporal construal, here we explored how action goals and temporal distance modulate the characteristics of future previews. Participants were required to imagine travelling to Egypt (in the near or distant future) to climb or photograph a pyramid. Afterwards, to probe the contents of prospection, participants provided a sketch of their imaginary experience. Results elucidated the impact of goal type and temporal distance on mental imagery. While a climbing goal prompted participants to draw a larger pyramid in the near than distant future, a photographic goal influenced only the compositional complexity of the sketches. These findings reveal how action goals and temporal distance shape the contents of future simulations.     

The flip side of perception-action coupling: locomotor experience and the ontogeny of visual-postural coupling.

The possible role of motor development on psychological function is once again a topic of great theoretical and practical importance. The revival of this issue has stemmed from a different approach to the topic, away from Gesell's interest in the long-term prediction of psychological functions from early motoric assessments, toward an attempt to understand how the acquisition of motor skills orchestrates psychological changes. This paper describes how the acquisition of one motor skill, prone locomotion, has been linked to developmental changes in an infant's ability to regulate posture based on information available in patterns of optic flow. It is argued that the onset of prone locomotion presses the infant to differentiate spatially delimited regions of optic flow to effectively and efficiently control the important subtasks nested within the larger task of locomotion, namely, steering, attending to the surface of support, and maintaining postural control. Following this argument, a research program is described that aims to determine if locomotor experience is causally linked to improvements in the ability to functionalize peripheral optic flow for postural control or whether locomotor experience is merely a maturational forecaster of such improvements. Finally, a hypothesis is put forward that links the emergence of wariness of heights to infants' ability to regulate posture on the basis of peripheral optic flow. The paper's overarching theoretical point is the principle of probabilistic epigenesis, which states that one developmental acquisition produces experiences that bring about a host of new developmental changes in the same and different domains.     

Stroop-like effects in a new-code learning task: A cognitive load theory perspective

To determine whether and how learning is biased by competing task-irrelevant information that creates extraneous cognitive load, we assessed the efficiency of university students with a learning paradigm in two experiments. The paradigm asked participants to learn associations between eight words and eight digits. We manipulated congruity of the digits’ ink colour with the words’ semantics. In Experiment 1 word stimuli were colour words (e.g., blue, yellow) and in Experiment 2 colour-related word concepts (e.g., sky, banana). Marked benefits and costs on learning due to variation in extraneous cognitive load originating from processing task-irrelevant information were evident. Implications for cognitive load theory and schooling are discussed.
