The relationship between emotion and cognition

The question that remains is whether cognition, and in particular cognitive appraisal, is necessary for the perception of emotion. If someone lacks the cognitive capacity to make a particular appraisal of an event, can they experience the emotion that is normally associated with that event?
Lazarus (1982, 1984, 1991, 1993) has added greatly to our understanding of emotion and coping processes.[coping processes ways of dealing with stressors – usually a mixture of being problem-focused and emotion-focused] He believes that an event must be understood before emotion can follow. On the other hand, Zajonc (e.g. 1980, 1984) argues that cognition and emotion are independent, with emotion even preceding cognition in some cases. This debate about whether cognition necessarily precedes or follows emotion turns on the definition of cognition. It is clear that conscious thought is not involved in some rapid emotional reactions. A sudden screech of brakes tends to produce an unthinking, uncontrolled emotional reaction. But it can also be argued that some appraisals might also occur unconsciously and immediately. If such appraisals are cognitions, then all emotion is preceded by and involves cognition. The alternative is that some emotions involve cognition and others o not. Perhaps this is an arid debate. In everyday life the interplay between emotion and cognition is very intricate. There is a huge difference between the internal lurch you would feel at a sudden loud noise in the middle of the night and the combination of thoughts and feelings you would experience if this turned out to be the precursor to your house going up in flames. In other words, a simple, immediate reflex action that might send a burst of adrenaline through the system is very different from the complexities of emotional reaction when the cortex is involved and specific hopes, fears, memories and expectations are implicated. The reflex system is primitive and very much centred on the ‘now’, whereas what might be termed ‘real’ emotion also involves the past and the future (through appraisals). It is clear that emotions can – or, as Lazarus would argue, must – result from appraisal. It is also clear that emotional states can affect thoughts and even subsequent emotions. You have judged that your partner as been unfaithful to you (appraisal) and this makes you react jealously (emotion). But when you are jealous (emotion) this may in turn stop you thinking (cognition) as clearly as you normally would, and you may become anxious (emotion) about that.
