This study tested the hypothesis that subjects improve their relative stability as they learn a dynamic pulling task. Healthy adult subjects practiced making brief horizontal pulls (<300 ms) on a handle to a range of target forces ranging from 20 to 80 percent of their estimated maximum for 5 days. They were instructed to always keep their feet flat, and begin and end their motion in an upright...

When multiple items are learned in sequential order, learning for one item tends to be disrupted by subsequently learned items. Such retrograde interference has been studied with paradigms conducted over a relatively short term. Resistance to interference is generally believed to be a measure of learning or consolidation. Here, we used a finger-tapping motor sequence paradigm to examine interfe...

11 Abstract. Selectively retrieving an item from long-term memory reduces the accessibility of competing traces, a phenomenon known as retrieval12 induced forgetting (RIF). RIF exhibits cue independence, or the tendency for forgetting to generalize to novel test cues, suggesting an inhibitory 13 basis for this phenomenon. An alternative view (Camp, Pecher, & Schmidt, 2007; Camp et al., 2009; Pe...

The following paper first introduces, and then goes on to test a structural model for goal orientation in sports that involves both personal and contextual variables. 511 subjects participated in this study, male and female athletes who play a variety of sports (352 men and 159 women). They ranged in age from 16 to 45-years old and completed the TEOSQ (Balaguer, Tomás & Castillo's version, 1995...
