Stimulus-onset asynchrony (SOA) is a measure used in experimental psychology. SOA denotes the amount of time between the start of one stimulus , S1, and the start of another stimulus, S2 (Figure 1). In this respect, a stimulus may consist of, e.g., a presented image, sound or printed word.
The time interval in between the onset of the cue and the onset of the target is defined as the stimulus onset asynchrony (SOA). Previous studies using this spatial cueing task found that in addition to cue validity, behavioural reactions were also affected by SOA. The effect of the SOA varies depending on whether a central or peripheral cue is ...
The theory assumes that at the outset of a response priming experiment, participants acquire rules of stimulus-response assignment, which quickly become automatized. Following this practice phase, the motor response can be prepared so far that only a single critical stimulus feature (e.g., diamond vs. square) is still needed to specify the ...
Shaded stages cannot overlap, but if they do, for example when the time intervening between the two tasks (SOA) is short, the one that has priority (i.e., the first task) will delay (SLACK) the execution of the second. This phenomenon is known as the psychological refractory period.
A wide range of research methods are used in psychology. These methods vary by the sources from which information is obtained, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they collect qualitative data, quantitative data or both.
The worked-example effect is a learning effect predicted by cognitive load theory. [1] [full citation needed] Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving [2] [page needed] and discovery learning.
Free association is the expression (as by speaking or writing) of the content of consciousness without censorship as an aid in gaining access to unconscious processes. [1] The technique is used in psychoanalysis (and also in psychodynamic theory ) which was originally devised by Sigmund Freud out of the hypnotic method of his mentor and ...
The Psychology Today article generated enormous publicity for the experiments, which are well known today, long after much of the formative work has been forgotten. Milgram's experiment was conceived in an era when a number of independent threads were converging on the idea that the world is becoming increasingly interconnected.
